High Sensitivity Fast Response Alcohol Gas Sensor used in Breathalyser - Mounted on Board with Sens. Adjust-Used with Arduino ETC.
Alcohol Gas Sensor
Features
High quality double panel design, with power indicator and TTL output signal.
Have DO switch signal(TTL) output and AO analog signal output.
TTL output signal for low level effectively. (when the low output electric signal lights at ordinary times, can be directly connect single chip microcomputer or relay module)
Analog output voltage with concentration, the higher concentration, the higher voltage.
Has better sensitivity with the liquefied petroleum gas, natural gas, city gas, smoke.
Has long service life and reliable stability
Rapid response recovery features
