This project is aimed at developing an IOT device which can monitor air pollution in real time and log data to a remote server. Remote monitoring was facilitated using classical motes in the past, which has some pitfalls like limited memory, processing speed and complex programming strategies. By using Internet of Things and recording sensor data to a remote server, the limitations of memory ...
· Community Air Sensor Network (CAIRSENSE) project: Air Quality Egg (nitrogen dioxide) The sensor device passes air over an internal metal oxide sensor, which provides a resistance change that is converted to an estimated NO2 concentration. Designed for indoor use or outdoor use with proper weather shielding. Data are reported in units of ppb.
Project: Using a low-cost sensor platform to explore the indoor environment in New Zealand schools Using commercial equipment to test the air quality in every New Zealand classroom would be prohibitively expensive. This project developed a low-cost sensor platform with remote logging and data transmission and tested it in 11 schools. The platform worked well, opening opportunities for ...
· Indoor Air Quality Sensors. Sensors are devices used to detect some type of input in the physical environment—for example, light, motion, temperature, etc.—and transmit that information into a signal that can be measured and transmitted electronically. In this case, an indoor air quality sensor would detect the presence of a particular pollutant. Different types of sensors measure ...
Indoor air quality is particularly important because most individuals spend over 80% of their time indoors. The goals of this project are twofold. First, the students will fabricate and test air quality sensors for measuring indoor air quality in the homes of 10 families living on the west side of the Salt Lake Valley. These sensors will include digital and color-coded displays. Second ...
· BME680 is an sensor by Bosch Sensortec especially for indoor air quality measurements. Instead of measuring CO2 levels it measures volatile organic compounds (VOC). Not only harmful substances like formaldehyde, lacquers and others but also substances exhaled by humans. interesting video about sensing VOC instead of CO2. all tests in the current version of the project are done with …

· Let’s first discuss a couple of common indoor air quality monitoring methods. Continuous or real-time indoor air quality monitoring is the process of gathering IAQ data 24 hours per day, 7 days per week. This is accomplished using IAQ sensors that collect minute-by-minute readings of your indoor air. Indoor air quality testing differs greatly.
