Zhengzhou Winsen Electronics Technology Co., Ltd www.winsensor.com MQ-5 Semiconductor Sensor for Combustible Gas Sensitive material of MQ-5 gas sensor is SnO2, which with lower conductivity in clean air. When the target combustible gas exist, The sensor’s conductivity is more higher along with the gas concentration rising. Please use simple electrocircuit, Convert change of conductivity to correspond output signal of gas concentration. MQ-5 gas sensor has high sensitity to Methane, Propane and Butane, and could be used to detect both Methane and Propane. The sensor could be used to detect different combustible gas especially Methane, it is with low cost and suitable for different application. Character Configuration – Good sensitivity to Combustible gas in wide range – High sensitivity to Methane, Butane and Propane – Long life and low cost – Simple drive circuit Application – Domestic gas leakage detector – Industrial Combustible gas detector – Portable gas detector Technic […]
