Monitor CO2 and TVOC With ESP32 : 8 Steps - Instructables

At room temperature, carbon dioxide (CO2) is a colorless, odorless, non-flammable gas, that must have a specific sensor to monitor it. SGP30 is a gas sensor intended for indoor air quality monitoring. SGP30 can detect a wide range of H2 and return an equivalent carbon dioxide reading calculated based on H2 concentration to the microcontroller over I2C. SGP30 has an ability to set humidity ...

How Does a TVOC Sensor Actually Work? - Kaiterra

What the sensor is actually measuring is the electrical resistance of this metal-oxide layer. This real time measurement and output of resistance is the first step in obtaining our TVOC reading. The change in resistance across the surface of the sensor is directly proportional to the change in concentration of the target gas(es). The exact ...

About TVOC and the Laser Egg+ Chemical

How the Laser Egg+ Chemical measures TVOC? A metal-oxide-semiconductor(MOS) sensor is used in the Laser Egg to measure TVOC concentration. To ensure measurements remain accurate throughout the sensor’s lifetime, the sensor is continually self-calibrating: the lowest reading is used as a baseline, and all given TVOC readings are relative to this baseline. For the first 5 minutes of powering ...
