Product introduction
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 breath gas sensor utilizes the MEMS process to fabricate a micro-hot plate on a Si substrate, and employs a metal oxide semiconductor material with low conductivity in clean air as the gas sensitive material. Upon detection of gas in the ambient air, the sensor’s conductivity undergoes changes, with higher gas concentrations resulting in increased sensor conductivity.
