MQ 8 HYDROGEN GAS SENSOR H2 GAS DETECTION SENSOR MODULE SENSOR FOR ARDUINO

Sepcifications

Size: 32mm X22mm X27mm

Main chip: LM393 gas sensor, MQ-8

Working voltage: DC5V

1. With signal output instructions.

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

3. TTL signal output valid for low level. (When the low output electric signal lights up in 4. Normal times, SCM can be directly picked up)

5. Analog 0 ~ 5v voltage, the higher the concentration, the higher the voltage.

6. High sensitivity to hydrogen

7. Can be resistant to ethanol vapor, LPG (petroleum), smoke interference

8. Has a long service life and reliable stability

9. Quick Response Recovery Features
