MQ-2 Smoke Liquefied Flammable Methane Gas Sensor

(0)
৳ 185.00

MQ-2 gas sensor sensitive material used in the clean air low conductivity tin oxide (SnO2). When there is the environment in which the combustible gas sensor, conductivity sensor with increasing concentration of combustible gases in air increases. Using a simple circuit to convert the change in conductivity of the gas concentration corresponding to the output … Continue reading MQ-2 Smoke Liquefied Flammable Methane Gas Sensor
