MQ6

Humans can detect many scents, but can have difficulties when it comes to differentiating gases. That’s why we use sensors like MQ6. It detects LPG and butane in the air. When heated to the optimum working temperature, it detects changes in air concentrations very quickly between 200 and 10000 ppm.

The DO pin stands for digital out. AO stands for analog out. The digital output is obtained by setting a threshold value using the potentiometer. The analog output will depend on the intensity of the gas around the sensor.

Product usage tips:

Preheating the sensor to the optimal working temperature takes 24 hours. The LED on the board will glow when gas is detected. It will remain off when it’s not. The board has two mounting holes for easy attachment to the project. It comes with four pins that need to be soldered.

You can use the board for years due to its long life. To prevent damage to the sensor, it should not be dipped in water or frozen. Highly corrosive gases will render the sensor useless. Cooking fumes and cigarette smoke will interfere with the sensor.

Humans can detect many smells, but may have difficulty distinguishing gases. That’s why we use sensors like the MQ6 that detects LPG and butane in the air. When heated to the optimal operating temperature, it very quickly detects changes in air concentration between 200 and 10,000 ppm.

The breakout board provides digital and analog information via the easyC system. Sensor readings are obtained via easyC.

Product usage tips:

When gas is detected, the LED will start glowing. It will remain off if it doesn’t detect anything. Four mounting holes enable easy mounting to surfaces. The board comes with three male headers.
