Description:
- MQ-136 MQ136 Hydrogen Sulfide Gas Sensor Module H2S Gas Sensor Detector
- Input voltage: DC5V Power consumption (current): 150mA
- DO output: TTL digital 0 and 1 (0.1 and 5V)
- AO output: analog level signal
- TTL output high and low level. (Can be directly connected to microcontroller or relay module)
- Special reminder: after the sensor is energized, it needs to be warmed up for about 20S for the measured data to be stable, and it is normal for the sensor to be hot because there is an electric heating wire inside, and it is not normal if it is hot.
Feature:
1、Using high-quality double-sided panel design, with power indication and TTL signal output indication;
2、With DO switch signal (TTL) output and AO analog signal output;
3、TTL output high and low level. (Can be directly connected to microcontroller or relay module)
4. Analog output voltage varies with concentration.
5, There is 1 screw hole for easy positioning;
6, Fast response recovery characteristics
Electrical performance:
Input voltage: DC5V Power consumption (current): 150mA
DO output: TTL digital 0 and 1 (0.1 and 5V)
AO output: analog level signal
Special reminder: after the sensor is energized, it needs to be warmed up for about 20S for the measured data to be stable, and it is normal for the sensor to be hot because there is an electric heating wire inside, and it is not normal if it is hot.
Wiring mode:
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 switch signal output
4、AO:Analog signal output
