Product Specification

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
