MQ-135 Air quality and hazardous gas detection sensor alarm module.
1. Size: 32mm X22mm X30mm length * width * height
2. The main chip: LM393, MQ135 gas sensing probe
3. Operating voltage: DC 5V
Features:
1. Signal output indicator instructions;
2. Dual signal output
3. TTL output valid signal is low; (Output low signal light, which can be accessed microcontroller IO port)
4. Analog output with increasing concentration, the higher the concentration, the higher the voltage;
