Overview
Water heater gas leakage and incomplete combustion detection module using electrochemical carbon monoxide sensor and combustible gas sensor developed a special detection of gas water heater incomplete combustion and gas leakage module. It uses the electrochemical principle to detect carbon monoxide gas produced by incomplete combustion in the air, and has good selectivity and stability.
Key Features
The module has sound and light alarm output, and PWM digital signal output mode.
Applications
Detection and alarm of gas leakage and incomplete combustion of household gas water heater.
