Monitor CO2 and TVOC With ESP32 : 8 Steps Instructables

+

At room temperature, carbon dioxide (CO2) is a colorless, odorless, nonflammable 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 ...
