Project 12:Analog Gas(MQ-2)Sensor
(1)Project Introduction
This gas sensor is used for household gas leak alarms, industrial
combustible gas alarms and portable gas detection instruments. Also, it is
suitable for the detection of liquefied gas, benzene, alkane, alcohol,
hydrogen, etc.,
The MQ-2 smoke sensor can be accurately a multi-gas detector, with the
advantages of high sensitivity, fast response, good stability, long life, and
simple drive circuit.
It can detect the concentration of flammable gas and smoke in the range of
300~10000ppm. Meanwhile, it has high sensitivity to natural gas, liquefied
petroleum gas and other smoke, especially to alkanes smoke.
