The MQ8 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.
- Input voltage: DC5V
- Power consumption (current): 150mA
- Both Analog and Digital Output
- It has good sensitivity to the detection of hydrogen.
- Long term life and reliable stability
