Description:
This CO2 sensor module can easily read CO2 and TVOC values through AT commands. This module also has three different threshold modes to choose from.

The module integrates with a SGP30 gas sensor and a SHT20 temperature and humidity sensor, which can measure the total VOC signal (TVOC), CO2 equivalent signal (CO2eq), temperature and humidity. The module also provides baseline settings and humidity cross sensitivity compensation. It can be widely used in fields such as smart home, home appliances, IoT and the like.

Precautions:
(1) Because the carbon dioxide sensor has a micro heating plate inside, the temperature measurement will be higher than the ambient temperature, which is normal.
(2) After sending , the module will use STH20 data to automatically perform humidity compensation, and the sending interval should be at least 1S.
(3) After sending , the module will automatically set the baseline, and the baseline should be set at least once every 7 days. Before setting the baseline, make sure that the sensor has been running for more than 12 hours.
