MQ137 Ammonia Gas Sensor Module CD4503BE IC the 709A delivers consistentMQ137 Ammonia Gas Sensor Module NH3 Detection The MQ137 is a semiconductor gas sensor designed to detect ammonia (NH3) a colorless, pungent gas commonly found in fertilizers, refrigeration systems, and industrial processes. It uses a SnO2 sensing element whose resistance changes in the presence of NH3. With analog and digital outputs, it is ideal for air quality monitoring, agricultural environments, and industrial safety systems using Arduino or
