The Natural gas module is a battery-operated detection device designed for the detection of natural gas (methane) in concentrations below 100% LEL (4.4% CH4 in the air). The sensor is not suitable for measuring propane and butane. The sensor is equipped with a test button as well as an audible alarm option realized with an 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 visual (LED) and audible (buzzer) alarms to inform of potential gas leakage as well as transmit data related to the actual state of the module and concentration of gas if the module is connected to an external receiver working with serial RS232 standard
