1. Size: 30mm X20mm X28mm

2. Main chip: LM393, MQ-131 gas sensor

3. Working voltage: DC 5V

4. Features:

1. With signal output indicator light;

2. Dual signal output (analog output and TTL level output);

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

4. The analog output increases with the concentration, the higher the concentration, the higher the voltage;

High sensitivity to ozone gas (detection concentration range 10-1000ppm)

6. It has a long service life and reliable stability;

7. Quick response and recovery features;

8. With mounting holes, it is convenient for fixed installation;

9. The probe can be plugged and unplugged, which is convenient for testing.
