Description: MQ137 Ammonia Gas Detection Sensor Module NH3 Gas Sensor Module Household1559 Adopt high-quality double-panel design, with power indicator and TTL signal output indicator.With DO switch signal (TTL) output and AO analog signal outputTTL output high and low level. (Can be directly connected to the microcontroller or relay module)The analog output voltage changes with the concentration. Fast response recovery feature.Has long service life and reliable stability.Electrical performance:Input voltage: DC5V Power consumption (current): 150mADO output: TTL digital quantities 0 and 1 (0.1 and 5V)AO output: analog level signalSpecial reminder: After the sensor is powered on, it needs to be preheated for about 20S, and the measured data is stable. It is normal for the sensor to heat up, because there is a heating wire inside, if it is hot, it will not be normal.Wiring:1. VCC: connect to the positive pole of the power supply (5V)2. GND: connect to the negative pole of the power supply3. DO: TTL switch signal output4. AO: analog signal outputModel Number: MQ137Type: Gas Sensorcolor:GreenMaterial:MetalPackage Contents:1 x MQ137 Ammonia Gas Senso Module
