Gas Sensor (MQ3 / Alcohol Vapour)

€12,40 Incl. tax
Article number: 101020006
Availability: In stock

Overview:

This product works on 5V only, so is not suitable for 3.3V boards like SODAQ and Seeeduino Stalker.

 

Grove Gas Sensor modules are useful for gas leakage detecting (in home and industry). They can detect LPG, i-butane, methane, alcohol, hydrogen, smoke and so on. Measurements can be taken as soon as possible based on its fast response time. For extra customizability, the sensitivity can be adjusted by the potentiometer. There are multiple Grove Gas Sensors created, all with similar functions. Some might measure Smoke, whilst others measure Alcohol vapour or carbon monoxide. You can switch the detector on the base according to specific target gases.

 

This particular module works with Alcohol Vapour as seen in the chart below. Please buy other models if you are interested in other types of gas detection.
