This is an Arduino hydrogen gas sensor with high sensitivity to hydrogen (H2) and low sensitivity to alcohol, LPG, and cooking fumes. Hydrogen is a highly flammable chemical element with the symbol H and atomic number 1, burning in air across a wide range of concentrations. The sensor's sensitivity can be adjusted via a potentiometer, and its output is proportional to the gas density. You can use analog reading to get data from it. To make it easier to use, it features a Gravity Interface for plug - and - play. The Arduino IO expansion shield is the perfect match when connecting this sensor to your Arduino microcontroller. Specifications include a 5V power supply, an analog interface type, and a pin definition of 1 - Output, 2 - GND, 3 - VCC. It has high hydrogen sensitivity, low sensitivity to other substances, is stable, and has a long lifespan. Its size is 40x20mm (1.57'x0.79'). Documents provided are Wiki Doc, MQ8 datasheet, and Schematic. The shipping list includes one Arduino Hydrogen Gas Sensor (MQ8).



Using this Arduino hydrogen gas sensor is quite easy. First, connect it to your Arduino microcontroller with the help of the Arduino IO expansion shield, which is the best match. The Gravity Interface allows for simple plug - and - play. You can then use analog reading to collect data about the hydrogen gas density. To adjust the sensitivity according to your needs, turn the potentiometer. Remember, hydrogen is highly flammable. So, always use the sensor in a well - ventilated area and away from open flames or heat sources. When it comes to maintenance, keep the sensor clean and free from dust. Avoid exposing it to extreme temperatures or humidity. If you need more information, refer to the provided Wiki Doc, MQ8 datasheet, and Schematic.
