Sensors at the Office: An Experiment in Indoor Air Quality ...

· But instead of lasting just one evening, these workshops serve to kick off weeks-long crowd science experiments around indoor air quality testing. A recent workshop at Temboo . We’ve been teaching participants how to use Temboo’s Kosmos IoT System and then sending them off with Nordic Thingy:52s, small Bluetooth devices with temperature, humidity, air pressure, and CO2 sensors…

CO2 Gas Sensor User Manual – Vernier

Keep in mind that indoor CO 2 gas concentration can vary a great deal and that there will be unit to unit variability of up to a few hundred parts per million CO 2. If the sensor is reading at or near the maximum value for the set range, the CO 2 concentration may be exceeding the maximum value for the setting. Place the sensor back into outside air or ambient room air and wait for the ...

Indoor Air Quality Monitoring: How To Test, Measure ...

· 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 ...

Development of an IoT-Based Indoor Air Quality Monitoring ...

· The CO sensor used in the study is also a semiconductor type, which is not the official standard CO sensor for indoor air quality measurements. TES-1372 from TES was used in the experiments for calibration and reliability testing because the Ministry recommended an NDIR-type measurement device. The same calibration method used for the VOC sensor was used for the CO sensor…

Seven Great Experiments Using the Wireless CO2 Sensor ...

· Here’s a quick look at some of the cool things you can do with the new Wireless CO2 Sensor! 1. Monitor Air Quality . An engaging way to introduce students to the sensor is to use the “closed” environment that you already have access to – your classroom or lab. This is also a great opportunity to use the data logging capabilities of the sensor. Find a central place in the room to place ...

Air Quality Sensors | Indoor Environment Group

Advances in low-cost sensor technologies have enabled development of indoor air quality monitors for the consumer market. These are many devices available for less than $300 that report concentrations of particulate matter (PM), temperature, humidity and sometimes carbon dioxide (CO2) or volatilate organic compounds (VOCs). To investigate the potential usefulness of these devices, we conducted ...
