MQ-7 Semiconductor Sensor for CO Gas Sensor Carbon monoxide Sensor Product information | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Description: Sensitive material of MQ-7 gas sensor is SnO2, which with lower conductivity in clean air. It make detection by method of cycle high and low temperature, and detect CO when low temperature (heated by 1.5V). The sensor’s conductivity is more higher along with the gas concentration rising. When high temperature (heated by 5.0V), it cleans the other gases adsorbed under low temperature. Please use simple electrocircuit, Convert change of conductivity to correspond output signal of gas concentration. Character: 1. High sensitivity to Natural gas 2. Long life and low cost 3. Simple drive circuit Application: 1. Domestic gas leakage detector 2. Industrial CO detector 3. Portable gas detector Technical Data:
