Summary
The Heltec QuickLink Series element includes a wide variety of sensors and actuators. With a unified packaging size and interface, the stamp hole allows it to be directly soldered onto your board like most modules, also it can be optionally equipped with a PH2.0 x 4 interface to make it compatible with the Grove Socket.
MEMS NH3 Gas Sensor uses the MEMS process to make a micro-hot plate on a Si substrate, and the gas sensitive material used is a metal oxide semiconductor material with low conductivity in clean air. When there is a detected gas in the ambient air, the conductivity of the sensor changes. The higher the concentration of the gas, the higher the conductivity of the sensor.
Main Features
- With unified packaging, stamp hole packaging (LGA) that can be directly soldered onto the circuit.
- Compatible with Grove socket through the PH2.0 x 4 interface.
- Strong structure and high sensitivity to Ammonia Gas

FAQ
The sensor can be seamlessly integrated with the Sensor Hub Series by simply plugging it into the board. This straightforward process allows for effortless connectivity and ease of use, allowing for precise data collection and analysis.
The Sensor Hub Series is a set of devices that are designed to collect and process data from various sensors. It is important to note that most of the Sensor Hub Series is supported, although some may have specific requirements as indicated. This means that users can expect reliable and high-quality performance from the majority of the devices in this series. However, it is recommended that users consult the manufacturer’s documentation to ensure compatibility with their specific needs. By doing so, users can maximize the functionality of the devices and ensure that they are able to meet their data processing requirements.
The sensor in question is not equipped with water and dust-resistant properties. In order to attain such capabilities, it would be necessary to employ the sensor within the protective enclosure of our Sensor Hub Products.
