Environmental conditions have a major impact on our well-being, comfort, and productivity.
This module is basically a breakout board for SGX Sensortech MICS-6814 Air Quality MOS Triple sensor. MiCS-6814 is a compact MOS sensor with three fully independent sensing elements on one package. 
It is a robust MEMS sensor for the detection of pollution from automobile exhausts and for agricultural/industrial odors.
MICS 6814 has a silicon gas sensor structure which consists of an accurately micromachined diaphragm with an embedded heating resistor and the sensing layer on top. 
The MiCS-6814 includes three sensors chips with independent heaters and sensitive layers. One sensor chip detects oxidizing gases (OX), the other sensor detects reducing gases (RED) and the other detects Ammonia (NH3).
