FSM-A-003 Indoor Air Quality Module Overview
FSM-A-003 is combined with sensor TGS2602 which detects indoor air quality, the unit helps user to decrease to understand the sensor and MCU function. The unit has wide application of air quality detecting and controlling.

According to air quality, the unit has 4 status: 
1.clean 
2. Slight pollution 
3.middle pollution
4.heavy pollution. 

The demo board(optional) has 4 LED display:
1.Green 
2.Yellow
3.Orange 
4.Red.

FSM-A-003 Indoor Air Quality Module Operation principle
As TGS2602 can detect the indoor air pollution, like VOCs, NH3, H2S, MCU process sensor and temperature signal, and judge the pollution level, and the unit outputs high level voltage correspond to pollution level. The unit gets to detect and control indoor air quality.
