Product Name: MQ131 Ozone Gas Detection Sensor Module (with analog and TTL level signal output)

First, the size: 32mm X 22mm X 30mm long * wide * high

Second, the main chip: high concentration / low concentration MQ131 gas sensor probe

Third, the working voltage: DC 5V

Fourth, the characteristics:

1, with a signal output indicator light;

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

3, TTL output valid signal is low; (output low when the signal light, can be connected to the microcontroller IO port)

4, the analog output decreases with increasing concentration, the higher the concentration the lower the voltage;

5, the ozone gas has a high sensitivity, ( high concentration probe 10ppm-1000ppm)

6, with long service life and reliable stability;

7, fast response to recovery characteristics;

8, with a mounting hole, easy to install;

9, the probe can be plug design, easy to test.
