MQ-8 Hydrogen H2 Gas Sensor Module for Arduino & Raspberry Pi – Gas Leak Detection & Monitoring (Delhi) - AB052

Description:

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. 

Using a simple circuit to convert the change in conductivity of the gas concentration corresponding to the output signal. MQ-8 hydrogen gas sensor of high sensitivity, the monitoring of the other hydrogen-containing gas is also very satisfactory.

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.
