MQ-8 Hydrogen Sensor Module

MQ-8 Hydrogen Gas Sensor Module

100-1000ppm H2 DC 5V Air Smoke Liquefied Flammable Methane Alarm Mq8

     It has high sensitivity to hydrogen in the air. It is also a sensor board used for detecting gases such as methane lpg alcohol. It has analog and digital outputs. It works with DC 5V. It can be used with mcu kits such as Arduino.

     As the SnO2 sensor component is exposed to gas, its conductivity changes. It performs the measurement depending on the changing conductivity. The initial warm-up time of the sensor is 20 seconds. After that it can perform normal gas measurement. Due to the combustion process in the gas chamber the sensor is hot and this temperature is normal.
