Measuring PPM from MQ Gas Sensors using Arduino (MQ-137 ...

09/02/2018· The MQ gas sensors can either purchased as a module or just as a sensor alone. If your purpose is to measure only ppm then it’s best to buy the sensor alone since the module is good for only using the Digital pin. So if you have purchased the module already then you have to perform a small hack which will be discussed further. For now, let’s assume you have purchased the sensor. The pinout ...

MQ Gas Sensor and Detectors - Proto-PIC

MQ Gas Sensor Range – Gas and Pollution Detectors. MQ 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. Simple 🙂 . All of the MQ gas sensors come in the same footprint, with the ...
