Taidacent MQ-131 Module Air Quality Testing TTL Level Output Ozone Gas Detection Ozone Sensor Module Analog O3 Ozone Sensor
OviewMain chip: MQ131 gas sensing probe
Working voltage: DC 5V
1. It has a signal output indicator indication;
2, dual signal output (analog output and TTL level output);
3. The TTL output valid signal is low level; (when the output low level, the signal light is on, it can be connected to the IO port of the single chip)
4. The analog output increases with increasing concentration, and the higher the concentration, the higher the voltage;
5. High sensitivity to ozone gas (detection concentration range 10PPB-2PPM)
6, has a long service life and reliable stability;
7, fast response recovery characteristics;
