DFRobot Fermion NH3 ammonia analogue gas sensor

The Fermion NH3 ammonia analogue gas sensor offers an advanced solution for monitoring ammonia concentrations in various environments. Featuring MEMS technology, this sensor is characterized by its compact size, low power consumption, and fast response times. It is ideal for use in cold storage, aquaculture, toilets, and other areas where ammonia needs to be monitored. This sensor measures ammonia concentrations qualitatively and can be used for early detection of leaks or for monitoring air quality. 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.

Info: 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.
