About this item

The DFRobot Fermion MEMS Ammonia (NH₃) Gas Detection Sensor Breakout is a compact and efficient sensor designed for detecting ammonia concentrations in the range of 1–300 ppm. Utilizing advanced micro-electromechanical system (MEMS) technology, this sensor offers high sensitivity and rapid response recovery. With dimensions of just 13×13×2.5 mm and an operating current of less than 20 mA, it is suitable for low-power applications. The sensor provides an analog voltage output and operates within a temperature range of -10°C to 50°C and a humidity range of 15% to 90% RH (non-condensing). It is ideal for applications such as ammonia leakage detection in cold storage, aquaculture risk control, and toilet odor monitoring. Please note that this sensor is designed for qualitative measurements; for quantitative analysis, consider using a calibrated NH₃ sensor.
