MQ131 High Concentration Ozone Gas Sensor Module (10-1000PPM)

Adopt high-quality double-panel design, with power indicator and TTL signal output indicator. With DO switch signal (TTL) output and AO analog signal output TTL 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 percompatible withmance: Input voltage: DC5V Power consumption (current): 150mA DO output: TTL digital quantities 0 and 1 (0.1 and 5V) AO output: analog level signal Special reminder: After the sensor is powered on, it needs to be preheated compatible with about 20S, and the measured data is stable. It is normal compatible with 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 supply 3. DO: TTL switch signal output 4, AO: analog signal output Material:Metal colour: green Package Contents: 1 x MQ131 High Concentration Ozone Sensor Only the above package content, other products are not included.
