The Fermion H2 hydrogen analogue gas sensor is a state-of-the-art sensor equipped with MEMS technology to accurately measure hydrogen concentrations. This sensor is ideal for monitoring hydrogen leaks, which is particularly important in industrial environments and in the development of fuel cell technologies. With a measurement range of 0.1 to 1000 ppm and a fast response time, the sensor is perfect for safety applications and air quality monitoring. The compact design and low power consumption make it ideal for portable and embedded applications.

To read the gas sensor with an Arduino, connect the analogue output pin of the sensor to an analogue input pin of the Arduino. Then use the analogRead() function in your Arduino sketch to measure and process the sensor values.

Please note that this sensor can only indicate whether a substance is present and only provides an approximate value. For accurate measurements, we recommend purchasing the Gravity series with factory calibrated electrochemical gas sensors.
