Description
MQ sensors, including the MQ3 sensor, are capable of detecting various gases. The MQ3 is specifically designed to detect alcohol vapours. This means it is sensitive to alcohols such as methanol, ethanol, and isopropanol. The MQ3 sensor is commonly used to measure the alcohol concentration in the air and is a useful tool for warning about the presence of alcohol in the environment.
Important Note: MQ sensors are not specialized for just one gas and can respond to other gases, but they only react to gases for which they are specifically designed. Therefore, it is crucial to use the MQ3 sensor solely for alcohol detection and to follow the manufacturer's instructions to achieve optimal measurement accuracy and reliability. It requires very little time to heat up to function properly.
The breakout provides digital and analog information via the easyC system. Data from the sensor can be accessed through easyC.
Recommendation for using this product:
When gas is detected, the LED lights up. If the sensor does not detect gas, the LED is off. Four mounting holes allow for easy attachment to surfaces. The board includes three header pins.
