This is a simple-to-use hydrogen gas sensor, suitable for sensing hydrogen concentrations in the air. The MQ-8 can detect hydrogen gas concentrations anywhere from 100-10000ppm.
This sensor has a high sensitivity and fast response time. The sensor’s output is an analog resistance. The drive circuit is very simple; all you need to do is power the heater coil with 5V, add a load resistance, and connect the output to an ADC.
- Power supply needs: 5V
- Interface type: Analog, Digital
- High sensitivity to Hydrogen (H2)
- Small sensitivity to alcohol, LPG,cooking fumes
- Stable and long life
- Size: 32x20mm
