Natural Gas Module Application Note

The NEW NGM_1 from SGX Sensortech is a natural gas module, battery operated detection device designed for detection of natural gas (methane) in concentrations below 100% LEL (4.4% CH4 in air). This module is not suitable for propane and butane detection. The sensor is equipped with a test button as well as an audible alarm option realized with embedded buzzer.

The heart of the device is an MP-7227 MEMS pellistor sensor which allows for low power operation on standard AA type batteries. The module is equipped with a visual (LED) and audible (buzzer) alarms to inform of potential gas leakage. It transmits data related to the actual state of the module and concentration of gas if the module is connected to a working external receiver with a serial RS232 standard connection. The estimated maintenance-free operation on 2xAA (2600mAh) batteries is 6 months.

The natural gas module monitors the concentration of methane in air atmosphere. The sensor operates in pulse mode measuring the actual concentration of gas during 1 second with 20 second intervals. The sensor is equipped with a buzzer and diode indicators. Click here for the application note which provides programming assistance.
