Mabee TVOC and eCO2 Module

Mabee TVOC and eCO2 Module

This Mabee TVOC and eCO2 module is an air quality monitor. Based on SGP30, this module provides TVOC(Total Volatile Organic Compounds) and CO2eq output; Based on the Sensirion temperature/ humidity sensors SHT31, it output highest-accuracy ±2% relative humidity and ±0.3°C accuracy temperature.

Which makes it a perfect choice for indoor air quality detection.

Unlike some other TVOC/eCO2 testing boards, that require the users to get the humility/ temperature by some other way, or use a “default parameter”, Makerfabs made the SGP30/ SHT31 sensor together on the same board, to ensure that the true humidity/ temperature can be measured simultaneously, to calibrate& ensure the VOA/eCO2 testing accurate and reliable. In the hardware design, as the SGP30 heat the air/ board in the testing, the slot is designed to isolate the 2 sensors, to ensure the SHT31 measures the true environment humidity/ temperature.

This module fits applications such as indoor air quality monitoring, air purifier…
