accurately a multi-gas detector, and has 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.
We will make a gas leakage detector with a MQ-2 gas sensor, a yellow LED
and a 1602 LCD.
