Gravity: MHZ9041A Methane Detection Sensor

The Gravity: Laser CH4(methane) sensor is based on Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology for methane gas detection. It adopts a dual-pass optical path structure, offering excellent gas selectivity, no oxygen dependence, and long service life. An integrated temperature sensor allows direct output of methane gas data (%LEL, Lower Explosive Limit) with temperature compensation. Compared with catalytic bead methane sensors, the laser detection principle ensures higher safety. The onboard Gravity interface supports I2C/UART data output, and the standoff mounting design makes it easy to fix the sensor onto any flat surface.
