Combustible Gas Sensor Smoke Sensor

Combustible Gas Sensor Smoke Sensor

Specification:

Semiconductor combustible gas sensor MQ-K2 gas-sensitive material used in the clean air low conductivity tin dioxide(SnO2). When there is the environmentin which the combustible gas sensor , conductivity sensor with increasingconcentration of combustible gases in air increases . Using a simple circuit to convert the change in conductivity of the gas concentration corresponding tothe output signal.This sensor can detect a variety of flammable gas , is a low-cost sensors for a variety of applications

Character:

1. MQ-K2 gas sensor with good sensitivity to Combustible gas in widerange,                                                  

2. High sensitivity to LPG, Propane andHydrogen,                                    

3. Long life and lowcost,
