Product Description
Have you ever wondered how much natural gas and methane are present in your living room? You can easily measure it! The MQ4 breakout board is a user-friendly sensor that detects natural gas and methane (CH4) in the air. Once it reaches operating temperature, it quickly detects changes in air concentration within the range of 200 to 10,000 ppm.
The breakout board provides digital and analog information through the easyC system. Sensor readings are obtained through 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.
