SOLDERED DEBO GAS MQ8 2 - Developer boards - gas sensor, hydrogen, MQ-8 15.11 EUR "In today's world, where safety in industrial environments is of paramount importance, early detection of hydrogen leakage plays a crucial role. The MQ8 breakout board sensor offers an efficient solution for monitoring hydrogen concentrations in the range of 100 to 1000 ppm. This device, compatible with Arduino (or a compatible board such as Dasduino), makes it possible to take precise measurements and thus prevent potentially dangerous situations.

• the sensor detects hydrogen concentrations from 100 to 1000 ppm
• digital and analog outputs are available via through pins
• a threshold can be set using a potentiometer for the digital output
• the device requires a preheating time of 48 hours for optimal function
• the sensor has a long service life, which means that it rarely needs to be replaced

The MQ8 sensor is equipped with digital (DO) and analog (AO) outputs, which facilitate integration into existing systems. The digital output is activated by setting a threshold value using a potentiometer, while the analog output reflects the measured gas concentration. An LED indication informs about the detection status of the gas. In addition, two mounting holes facilitate the secure attachment of the board. It should be noted that the sensor requires a preheating time of 48 hours to reach its optimum operating temperature. Furthermore, the sensor should not be immersed in water or frozen, as this can lead to damage. Exposure to highly corrosive gases should also be avoided in order not to impair the service life of the sensor.

Technical data

• Operating voltage: 5 V
• Logic voltage level: 5 V
• Operating temperature: -10 ... 50 °C
• Gas detection: Hydrogen
• Gas detection range: 100 ... 1000 ppm
• Preheating time: 48 h
• Mounting holes: 2
• Dimensions: 22 x 38 mm

In summary, the MQ8 sensor offers a reliable solution for early detection of hydrogen leaks. Its compatibility with Arduino (or a similar board such as Dasduino) allows easy integration into existing systems. Its long lifetime and ease of use make it a valuable tool for the industry to ensure safety and efficiency.
