MQ-8 Gas Sensor Module
The MQ-8 gas sensor module is a device that can detect the presence of hydrogen gas in the air. It is commonly used in applications such as gas leak detectors, safety devices, and industrial control systems. The MQ-8 sensor operates by using a chemical reaction between the hydrogen gas and a conductive metal oxide to produce a current. The magnitude of the current is proportional to the concentration of hydrogen gas in the air. The sensor can be used to detect hydrogen gas concentrations in the range of 100-10000 ppm.This sensor can detect a wide range of hydrogen gas, city gas, in particular, is a low-cost sensor for a variety of applications. Suitable for home or industrial hydrogen leakage monitoring devices. Can not interfere with ethanol vapor, soot, carbon monoxide, and other gases.
Applications:
- Detect leakages in the industry
- Used in mines
- Can be used in refrigerators and AC
Package Includes:
- 1 x MQ8 Gas Sensor Module

1. What are gas sensors? How do they work?
- Gas sensors (also known as gas detectors) are electronic devices that detect and identify different types of gasses. They are commonly used to detect toxic or explosive gasses and measure gas concentration.
Gas sensor detects the presence or concentration of gases in the atmosphere. Based on the concentration of the gas the sensor produces a corresponding potential difference by changing the resistance of the material inside the sensor, which can be measured as output voltage. Based on this voltage value the type and concentration of the gas can be estimated.
2. How to use MQ-8 Gas Sensor?
- Power the module with 5V and you should notice the power LED on the module to glow and when no gas it detected the output LED will remain turned off meaning the digital output pin will be 0V. Remember that these sensors have to be kept on for pre-heating time before you can actually work with it. Now, introduce the sensor to the gas you want to detect and you should see the output LED to go high along with the digital pin, if not use the potentiometer until the output gets high. Now every time your sensor gets introduced to this gas at this particular concentration the digital pin will go high (5V) else will remain low (0V).
