Hydrogen is all around us, and it’s very flammable. Its leakage can be very dangerous to both life and property. That’s why it's important to detect any leakage to prevent in the industry. To help with that, hydrogen sensors like the MQ8 breakout board are used. The sensor detects hydrogen at the range of 100-1000 ppm.

The digital and analog outs are on the breakout through-hole pins. They are marked as DO and AO respectively. By setting a threshold value with a potentiometer, you can get the digital output. The analog output will depend on how much gas is detected around the sensor.
