Mabee_TVOC and eCO2 SGP30 & Temperature and Humidity SHT31

his Mabee 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…
