High quality dual panel design with power indicator and TTL signal output indication.
TTL output valid signal is low level, (output low signal light, which can be accessed microcontroller IO port).
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, and other gases harmful gas detection. Gas-sensitive element test concentration range: 10 to 1000ppm.
Long service life, stable and reliable. Has fast response and recovery features.
