Gas and Liquid

Gas sensors are devices that can detect the presence and concentration of various hazardous gases and vapors, such as toxic or explosive gases, volatile organic compounds (VOCs), humidity, and odors. Gas Sensor Detectors have a high sensitivity and fast response time. The sensor’s output is an analog resistance. The drive circuit is very simple, all you need to do is power the heater coil with 5V, add a load resistance, and connect the output to an ADC.

With these Gas Sensor Breakout you will be able to utilize each oversized, oddly spaced pins featured on every MQ gas sensor product. This is an extremely handy and economical board to have around when detecting multiple types of gases. All you need is the VCC at 5V, GND, and a resistor to an ADC, that is it!
