Measurements are available through the Aqara app and smart home ...
TVOC, Temperature and Humidity Sensor: The Aqara TVOC Air Quality Monitor detects the concentration of the Volatile Organic Compounds (VOCs) which are harmful, carcinogenic air pollutants that evaporate at normal indoor atmospheric conditions, and measures temperature and humidity, which can also be used in smart home automations.
Yes. The TVOC sensor can only measure changes and requires a one-time 4-hour calibration before initial use. So all readings during usage depend on the initial environment. That’s why in the manual it’s recommended to calibrate in a well-vented place away from people.
mentioned earlier as an advantage, turns out to be a disadvantage when issues like measurement accuracy and calibration are taken into account. Broad sensitivity is also a disadvantage if the sensors react to short-term “non-problematic” VOCs emissions like ethanol, perfume or limonene from oranges. If MOS VOC sensors should be widely applied in practice, as not only air quality indicators ...

This is a gas sensor that can detect a wide range of Volatile Organic Compounds (VOCs) and H2 and is intended for indoor air quality monitoring. When connected to your microcontroller (running our library code) it will return a Total Volatile Organic Compound (TVOC) reading and an equivalent carbon dioxide reading (eCO2) over I2C. The SGP30 has a 'standard' hot-plate MOX sensor, as well as a ...

Figured it out, or so I thought. A few moments later, unit flips back to home screen without saving my updated date / time. 3) Observed TVOC flitting about, wasn't a stable value. May be my stinky office, but didn't seem to have stability. The manual suggests three minutes of warm up time, as is typical for the sensors these devices use. But I ...
