MQ8 Hydrogen (H2) Gas Sensor

Description:

• The MQ8 sensor is its semiconductor sensing component, designed to specifically react to the presence of hydrogen molecules in the air.
• When air comes into contact with the sensing layer, it changes the resistance of the sensor, allowing you to measure the change and detect the presence of the gas.
• As these gasses interact with the sensor, changes in its electrical conductivity occur.
• The sensor converts these changes into analog signal, for detection of hydrogen concentrations.
• Connecting the sensor to an analog-to-digital converter (ADC) on a microcontroller enables users to obtain digital readings of concentrations.
• There is a potentiometer on the sensor which allows users to adjust the sensitivity based on specific requirements.
