mq135 sensor

Input voltage: DC5V power (current): 150mA
Analog output with increasing concentration, the higher the concentration, the higher the voltage.
A hazardous gas detection apparatus for the family, the environment. Suitable for ammonia, aromatic compounds, sulfur, benzene vapor, smoke and other gases harmful gas detection. Gas-sensitive element test concentration range: 10 to 1000ppm
TTL output valid signal is low level, (output low signal light, which can be accessed microcontroller IO port).
