{"title":"Hydrogen Gas Sensor - MQ-8","handle":"hydrogen-gas-sensor-mq-8","url":"/products/hydrogen-gas-sensor-mq-8","description":"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.   This sensor comes in a package similar to our MQ-3 alcohol sensor, and can be used with the breakout board below.
