Description

DESCRIPTION

This module is useful for gas leakage detection where it generates lower conductivity in clean air and vice versa. The detection works by method of cycling high and low temperature on the sensor, and detect CO when low temperature (heated by 1.5V). The sensors conductivity increases along with the gas concentration rising. When high temperature (heated by 5.0V), it detects Methane, Propane etc combustible gas and cleans the other gases absorbed under low temperature. MQ-9 gas sensor has high sensitivity to Carbon Monoxide, Methane and LPG. The sensor could be used to detect different gases that contains CO and combustible gases. It is low cost and suitable for different application.
