Used in gas leakage detecting equipments in family and industry, suitable for detecting
of LPG, i-butane, propane, methane ,alcohol, Hydrogen, smoke.
Due to its high sensitivity and fast response time, measurement can be taken as soon as possible. The sensitivity of the sensor can be adjusted by potentiometer.
Works on 5V and can be used with most common microcontrollers.
The sensor value only reflects the approximated trend of gas concentration in a permissible error range, it DOES NOT represent the exact gas concentration. The detection of certain components in the air usually requires a more precise and costly instrument, which cannot be done with a single gas sensor. If your project is aimed at obtaining the gas concentration at a very precise level, this gas sensor is not recommend.
