Product Description:

MQ-131 Module Ozone Gas Detection Ozone Sensor Module Air Quality Detection

Features:

Main chip: MQ131 gas sensor

Operating voltage: DC 5V

Features:

1, with signal output indicator light;

2, dual signal output (analog output and TTL level output);

3, TTL output effective signal is low level; (Output low normal signal light, can be connected to MCU IO port)

4, analog output increases with the increase of concentration, the higher the concentration, the higher the voltage;

5, high sensitivity to ozone gas, (detection concentration range of 10PPB-2PPM)

6, with a long service life and reliable stability;

7, fast response recovery characteristics;
