20180408· The files are used to obtain parts per million (ppm) of the Carbon Monoxide gas using the analog input of the MQ7 gas sensor. Pre requisites. The following involves the basic connection of MQ7 and Arduino board and the use of this library. Connect the Vcc and GND pins of the MQ7 sensor to the Arduino 5v and GND pin respectively.

This schematic diagram is the same as with the MQ3 alcohol sensor and MQ6 LPG sensor. There are two ways to read the output from the MQ7. One is through the DOUT pin which gives a high when the concentration threshold is reached and low otherwise. The threshold can be varied by adjusting the trimmer on the breakout board which is Rp in the ...

This sensor measures the gas concentration based on resistance ratio. This ratio includes R0 (sensor resistance in 1000ppm concentration of LPG) and Rs (Internal resistance of the sensor which changes by gas concentration). In clean air, after preheating, upload the following code and wait for about 15 minutes until R0 reaches a fixed value.

20200911· MQ4 Methane Sensor Overview. At the heart of the MQ4 is a heater and electrochemical sensor. When the target gas enters the membrane and reaches the sensor, it undergoes a redox reaction which creates current. This current is stronger for sensors at specific gases. In the case of the MQ4, it’s more sensitive to methane, butane and propane.
