See Table3 for the average number of files captured by each hub. sharing sensitive information, make sure youre on a federal There are no placeholders in the dataset for images or audio files that were not captured due to system malfunction, and so the total number of sub-folders and files varies for each day. Each HPDmobile data acquisition system consists of: The sensor hubs run a Linux based operating system and serve to collect and temporarily store individual sensor readings. We implemented multistate occupancy models to estimate probabilities of detection, species-level landscape use, and pair occupancy of spotted owls. The DYD data is collected from ecobee thermostats, and includes environmental and system measurements such as: runtime of heating and cooling sources, indoor and outdoor relative humidity and temperature readings, detected motion, and thermostat schedules and setpoints. The sensors are connected to the SBC via a custom designed printed circuit board (PCB), and the SBC provides 3.3 Vdc power to all sensors. (g) H6: Main level of studio apartment with lofted bedroom. Through sampling and manual verification, some patterns in misclassification were observed. This series of processing allows us to capture the features from the raw audio signals, while concealing the identity of speakers and ensuring any words spoken will be undecipherable. Interested researchers should contact the corresponding author for this data. From these verified samples, we generated point estimates for: the probability of a truly occupied image being correctly identified (the sensitivity or true positive rate); the probability of a truly vacant image being correctly identified (the specificity or true negative rate); the probability of an image labeled as occupied being actually occupied (the positive predictive value or PPV); and the probability of an image labeled as vacant being actually vacant (the negative predictive value or NPV). Currently, rice panicle information is acquired with manual observation, which is inefficient and subjective. An example of this is shown in Fig. This paper describes development of a data acquisition system used to capture a range of occupancy related modalities from single-family residences, along with the dataset that was generated. (seven weeks, asynchronous video lectures and assessments, plus six 1.5 hour synchronous sessions Thursdays from 7-8:30pm ET) OMS perceives the passengers in the car through the smart cockpit and identifies whether the behavior of the passengers is safe. The code base that was developed for data collection with the HPDmobile system utilizes a standard client-server model, whereby the sensor hub is the server and the VM is the client. The cost to create and operate each system ended up being about $3,600 USD, with the hubs costing around $200 USD each, the router and server costing $2,300 USD total, and monthly service for each router being $25 USD per month. More than 100 million people use GitHub to discover, fork, and contribute to over 330 million projects. The binary status reported has been verified, while the total number has not, and should be used as an estimate only. Volume 112, 15 January 2016, Pages 28-39. The homes included a single occupancy studio apartment, individuals and couples in one and two bedroom apartments, and families and roommates in three bedroom apartments and single-family houses. If you need data services, please feel free to contact us atinfo@datatang.com. E.g., the first hub in the red system is called RS1 while the fifth hub in the black system is called BS5. Most sensors use the I2C communication protocol, which allows the hub to sample from multiple sensor hubs simultaneously. Readers might be curious as to the sensor fusion algorithm that was created using the data collected by the HPDmobile systems. In the last two decades, several authors have proposed different methods to render the sensed information into the grids, seeking to obtain computational efficiency or accurate environment modeling. As part of the IRB approval process, all subjects gave informed consent for the data to be collected and distributed after privacy preservation methods were applied. (a) Average pixel brightness: 106. 2 for home layouts with sensor hub locations marked. The framework includes lightweight CNN-based vehicle detector, IoU-like tracker and multi-dimensional congestion detection model. Spatial overlap in coverage (i.e., rooms that had multiple sensor hubs installed), can serve as validation for temperature, humidity, CO2, and TVOC readings. Thus the file with name 2019-11-09_151604_RS1_H1.png represents an image from sensor hub 1(RS1)in H1, taken at 3:16:04 PM on November 9, 2019. In 2020, residential energy consumption accounted for 22% of the 98 PJ consumed through end-use sectors (primary energy use plus electricity purchased from the electric power sector) in the United States1, about 50% of which can be attributed to heating, ventilation, and air conditioning (HVAC) use2. You signed in with another tab or window. All data was captured in 2019, and so do not reflect changes seen in occupancy patterns due to the COVID-19 global pandemic. Ground-truth occupancy was Occupancy detection, tracking, and estimation has a wide range of applications including improving building energy efficiency, safety, and security of the After training highly accurate image classifiers for use in the ARPA-E SENSOR project, these algorithms were applied to the full collected image sets to generate binary decisions on each image, declaring if the frame was occupied or vacant. Keywords: occupancy estimation; environmental variables; enclosed spaces; indirect approach Graphical Abstract 1. SciPy 1.0: Fundamental algorithms for scientific computing in Python. WebOccupancy Experimental data used for binary classification (room occupancy) from Temperature, Humidity, Light and CO2. An Artificial Neural Network (ANN) was used in this article to detect room occupancy from sensor data using a simple deep learning model. Using environmental sensors to collect data for detecting the occupancy state Training and testing sets were created by aggregating data from all hubs in a home to create larger, more diverse sets. Due to the presence of PII in the raw high-resolution data (audio and images), coupled with the fact that these were taken from private residences for an extended period of time, release of these modalities in a raw form is not possible. WebThe field of machine learning is changing rapidly. Luis M. Candanedo, Vronique Feldheim. Abstract: Experimental data used for binary classification (room occupancy) from / Chou, Chao Kai; Liu, Yen Liang; Chen, Yuan I. et al. In order to confirm that markers of human presence were still detectable in the processed audio data, we trained and tested audio classifiers on pre-labeled subsets of the collected audio data, starting with both unprocessed WAV files (referred to as P0 files) and CSV files that had gone through the processing steps described under Data Processing (referred to as P1 files). For a number of reasons, the audio sensor has the lowest capture rate. The occupants cover a range of ages and relationships and consisted of couples, roommate households, and one family with adult children who were home during part of the testing duration. (a) and (b) are examples of false negatives, where the images were labeled as vacant at the thresholds used (0.3 and 0.4, respectively). Please to use Codespaces. and transmitted securely. Contact us if you (c) Custom designed printed circuit board with sensors attached. Because the environmental readings are not considered privacy invading, processing them to remove PII was not necessary. 2021. To aid in retrieval of images from the on-site servers and later storage, the images were reduced to 112112 pixels and the brightness of each image was calculated, as defined by the average pixel value. The data includes multiple age groups, multiple time periods and multiple races (Caucasian, Black, Indian). The homes and apartments tested were all of standard construction, representative of the areas building stock, and were constructed between the 1960s and early 2000s. (c) and (d) H3: Main and top level (respectively) of three-level home. In total, three datasets were used: one for training and two for testing the models in open and closed-door occupancy scenarios. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Saha H, Florita AR, Henze GP, Sarkar S.

While many datasets exist for the use of object (person) detection, person recognition, and people counting in commercial spaces1921, the authors are aware of no publicly available datasets which capture these modalities for residential spaces. See Technical Validation for results of experiments comparing the inferential value of raw and processed audio and images. Work fast with our official CLI. Individual sensor errors, and complications in the data-collection process led to some missing data chunks. The system used in each home had to do with which was available at the time, and most of the presented data ended up being collected with HPDred. All image processing was done with the Python Image Library package (PIL)30 Image module, version 7.2.0. This operated through an if-this-then-that (IFTTT) software application that was installed on a users cellular phone. All code used to collect, process, and validate the data was written in Python and is available for download29 (https://github.com/mhsjacoby/HPDmobile).

Audio and image files are stored in further sub-folders organized by minute, with a maximum of 1,440minute folders in each day directory. Finally, audio was anonymized and images downsized in order to protect the privacy of the study participants. Audio processing steps performed on two audio files. The YOLO algorithm generates a probability of a person in the image using a convolutional neural network (CNN). The proportion of dark images to total images each day was calculated for all hubs in all homes, as well as the proportion of missing images. Audio files were processed in a multi-step fashion to remove intelligible speech. Are you sure you want to create this branch? Ground-truth occupancy was obtained from time stamped pictures that were taken every minute. You signed in with another tab or window. Our best fusion algorithm is one which considers both concurrent sensor readings, as well as time-lagged occupancy predictions.

The project was part of the Saving Energy Nationwide in Structures with Occupancy Recognition (SENSOR) program, which was launched in 2017 to develop user-transparent sensor systems that accurately quantify human presence to dramatically reduce energy use in commercial and residential buildings23. STMicroelectronics. (d) and (e) both highlight cats as the most probable person location, which occurred infrequently. In addition to the environmental readings shown in Table1, baseline measurements of TVOC and eCO2, as collected by the sensors, are also included in the files. See Fig. The median cut-off value was 0.3, though the values ranged from 0.2 to 0.6. To address this, we propose a tri-perspective view (TPV) representation which Based on this, it is clear that images with an average pixel value below 10 would provide little utility in inferential tasks and can safely be ignored. Thus, data collection proceeded for up to eight weeks in some of the homes. See Fig. An official website of the United States government. Learn more. Due to misclassifications by the algorithm, the actual number of occupied and vacant images varied for each hub. Besides, we built an additional dataset, called CNRPark, using images coming from smart cameras placed in two different places, with different point of views and different perspectives of the parking lot of the research area of the National Research Council (CNR) in Pisa. Because data could have been taken with one of two different systems (HPDred or HPDblack), the sensor hubs are referred to by the color of the on-site server (red or black). Howard B, Acha S, Shah N, Polak J. Figure4 shows examples of four raw images (in the original 336336 pixel size) and the resulting downsized images (in the 3232 pixel size).

This is a repository for data for the publication: Accurate occupancy detection of an office room from light, temperature, humidity and CO2 The 2022 perception and prediction challenges are now closed, but the leaderboards remain open for submissions. Even though there are publicly The final data that has been made public was chosen so as to maximize the amount of available data in continuous time-periods. The smaller homes had more compact common spaces, and so there was more overlap in areas covered. The TVOC and CO2 sensor utilizes a metal oxide gas sensor, and has on-board calibration, which it performs on start-up and at regular intervals, reporting eCO2 and TVOC against the known baselines (which are also recorded by the system). While the data acquisition system was initially configured to collect images at 336336 pixels, this was deemed to be significantly larger resolution than necessary for the ARPA-E project, and much larger than what would be publicly released. Described in this section are all processes performed on the data before making it publicly available. Therefore, the distance measurements were not considered reliable in the diverse settings monitored and are not included in the final dataset. Using a constructed data set to directly train the model for detection, we can obtain information on the quantity, location and area occupancy of rice panicle, all without concern for false detections. The driver behaviors includes Dangerous behavior, fatigue behavior and visual movement behavior. Trends in the data, however, are still apparent, and changes in the state of a home can be easily detected by. (d) Waveform after downsampling by integer factor of 100. SMOTE was used to counteract the dataset's class imbalance. occupancy was obtained from time stamped pictures that were taken every minute. This paper describes development of a data acquisition system used to capture a range of occupancy related modalities from single-family residences, along with the dataset that was generated. For each home, the combination of all hubs is given in the row labeled comb. Audio processing was done with SciPy31 io module, version 1.5.0. Energy and Buildings. The sensor fusion design we developed is one of many possible, and the goal of publishing this dataset is to encourage other researchers to adopt different ones. First, minor processing was done to facilitate removal of data from the on-site servers. & Hirtz, G.

(b) H2: Full apartment layout. The data includes multiple ages and multiple time periods. The setup consisted of 7 sensor nodes and one edge False negatives were not verified in similar fashion, as false negatives from the images (i.e., someone is home but the camera does not see them) were very common, since the systems ran 24-hours a day and people were not always in rooms that had cameras installed. Several of the larger homes had multiple common areas, in which case the sensors were more spread out, and there was little overlap between the areas that were observed. In one hub (BS2) in H6, audio was not captured at all, and in another (RS2 in H5) audio and environmental were not captured for a significant portion of the collection period. Section 5 discusses the efficiency of detectors, the pros and cons of using a thermal camera for parking occupancy detection. WebThe publicly available dataset includes: grayscale images at 32-by-32 pixels, captured every second; audio files, which have undergone processing to remove personally identifiable (b) Final sensor hub (attached to an external battery), as installed in the homes.
