Water Heater Gas Leakage and Incomplete Combustion Detection Module
Description
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。
Sensor characteristics
The module has sound and light alarm output, and PWM digital signal output mode.
Main applications
Detection and alarm of gas leakage and incomplete combustion of household gas water heater

Function description
After the module is powered on, the buzzer rings, the indicator flashes, and then the green indicator flashes into the preheating state. About 30 seconds later, the CO sensor is preheated, the green indicator will steady on, then the CO concentration can be detected and warned. About 3 minutes later, the CH4 sensor is preheated, and the CH4 concentration can be detected and warned. After pressing the self-test button, the CO indicator and CH4 indicator will blink red, and the buzzer will sound. After 10 seconds, the self-test will stop and return to the normal working state. When the concentration of CO or CH4 exceeded the alarm value, the corresponding indicator blinked red and the buzzer sounded at the same time, and the alarm was automatically stopped after the concentration was reduced.
PWM frequency refer to the following table:
| Working Status | Preheat | Normal work | COAlarm1 | COAlarm2 | CH4Alarm | Fault |
|---|---|---|---|---|---|---|
| PWMfrequency（Hz） | 100 | 100 | 20 | 14 | 8 | 33 |
Cautions:
- Do not insert, remove or touch the sensor on the module.
- Do not change or shift the installation status of electronic components.
- Avoid contact with organic solvents (including silica gel and other adhesives), coatings, pharmaceuticals, oils and high concentration gases.
- The module can not withstand excessive impact or vibration.
- The module needs to be preheated for more than 20 minutes when it is first powered on.
- Do not use the module in the system involving personal safety.
- Do not install the module in a strong air convection environment.
- Do not place the mold in high concentration of organic gas for a long time.
