MQ131 High Concentration Ozone Sensor Gas Sensor Module for Ozone High Concentration Analog TTL Level Output 10-1000PPM

MQ131 High Concentration Ozone Sensor Gas Sensor Module for Ozone High Concentration Analog TTL Level Output 10-1000PPM Description

Adopt high-quality double-panel design, with power indicator and TTL signal output indicator.
With DO 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 performance:
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 , it needs to be preheated for about 20S, and the measured data is stable. It is normal for the sensor to heat , 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 signal output
4, AO: analog signal output
Material:Metal
colour: green
