Presenting MQ sensors: low-cost gas and pollution detectors - …

16/02/2018· Let’s discover a set of low-cost gas and pollution detectors that may be easily accessed from the Arduino World. Detecting and measuring pollution and the main gases (the ones we may come across in our daily life) is always relevant; such operations are carried out by means of specific sensors, that are often very expensive. Luckily, for a while it is possible to find low-cost, reliable sensors for …

How to Use the MQ-7 Carbon Monoxide Sensor - Arduino, …

Arduino Sketch for MQ-7. Before we can use this formula in a sketch, we need to determine R0 of the MQ-7 sensor first. This varies between devices so there is a need for actual testing. From the log-log plot, we can see that RS/R0 is constant in air and is equal to 1. Since by definition, R0 is the resistance of the sensor in clean air, then ...

LPG Sensor with MQ-6 and Arduino | Microcontroller Tutorials

MQ-6 Gas Leak Detector. If you want to detect only the presence of LPG in the air, you only need to connect the AO pin to any analog pin of the Arduino UNO. Then you must determine the threshold value by placing the MQ-6 near a safe LPG source (like an unignited gas stove) and record the reading. Note that the MQ-6 needs at least 20 seconds to ...
