Gas sensor registers the presence of various gases, such as oil and gasoline vapors, butane, propane, methane, ethanol(alcohol), hydrogen, smoke. It registers gases the best while they are in the liquid form, but since we cannot find them in that state that often, it measures a good concentration of substances in a gaseous state. It takes a short time to heat up in order to work correctly.

Have you ever wondered how much natural gas and methane are in your living room? You can easily measure that! The MQ4 breakout board is a simple-to-use sensor that detects the natural gas and methane (CH4) in the air. Once heated to working temperature, it detects changes in air concentrations very quickly between 200 and 10000 ppm.

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.

Gas sensor MQ7 detects the presence of Carbon Monoxide (CO) in the air. The best results are given when alcohol is in liquid form, however, it still does an amazing job when measuring in gas form. It needs a bit of time to warm up in order to work correctly.

Hydrogen is all around us, and it’s very flammable. Its leakage can be very dangerous to both life and property. That’s why it's important to detect any leakage to prevent in the industry. To help with that, hydrogen sensors like the MQ8 breakout board are used. The sensor detects hydrogen at the range of 100-1000 ppm.

We are surrounded by invisible gases everywhere. While we generally don’t have to worry about them, under the right circumstances, they can be very combustible and dangerous. The MQ9 breakout board detects carbon monoxide, methane, propane, and other flammable gases so the right measures can be taken in time. The sensor detects carbon monoxide at 10-1000 ppm and other combustible gasses at 100-10000 ppm.

This breakout for the MQ131 sensor responds to the presence of ozone in the air. As the ozone concentration increases, the resistance changes and the ozone concentration can be measured by measuring the analogue output voltage. The sensor is of good precision and is normally used in ozone concentration detectors. There is a 3362 potentiometer on the board with which the digital signal threshold can be set. There is a digital and analogue output via the male pins.
