Product introduction
What’s this?
The CH4 Gas Sensor, utilizing the GM-502B chip, is part of the Heltec Quick Link Series. The module features stamp hole packaging (LGA) for direct circuit soldering or compatibility with the Grove socket via the PH2.0 x 4 interface.
Main Features
The Heltec QuickLink Series element offers a diverse range of sensors and actuators. With a standardized packaging size and interface, the stamp hole allows for direct soldering onto your board like most modules. Additionally, it can be optionally equipped with a PH2.0 x 4 interface to ensure compatibility with the Grove Socket. The MEMS CH4 gas sensor utilizes the MEMS process to fabricate microheat plates on the Si base substrate. The gas-sensitive material employed is a metal oxide semiconductor with low conductivity in clean air.
