Gravity MQ-8 Gas Sensor Module – Hydrogen Gas

The awesome advancements of modern technology and electronic sensors allow Makers to see more than our eyes ever could. Sometimes, that ability is lifesaving. While many natural gases are harmless by themselves, we instinctively understand that breathing healthy air is important for living happy lives. Everyone could benefit from being able to measure the particles in the air around them to identify just how healthy their working or living environments are. Hydrogen gas, however, is also known for its flammable nature, making it particularly dangerous in high concentrations. This MQ-8 Gas Sensor Module is an environmental sensor that detects the presence of hydrogen gas.

The Gravity MQ-8 Gas Sensor Module offers fast response times for detecting hydrogen gas with high sensitivity, and alcohol, LPG and cooking fumes with low sensitivity. The MQ-8 Gas Sensor sensitivity can be adjusted with the onboard potentiometer. An easy gravity analog interface allows you to connect the gas sensor to Arduino microcontrollers. The Arduino IO expansion shield is a perfect match to integrate additional features to your Arduino project. These features, in conjunction with the long lifespan of materials used to build the Gas Sensor, make it an excellent investment for anyone who might be concerned with the saturation levels of dangerous gases within a home, workplace or even factory environment.
