How to Calibrate And Use MQ9 Gas Sensor w/ Arduino

翻译 · The MQ9 sensor is sensitive to carbon monoxide and flammable gases. It can detect the detect carbon monoxide density from 10ppm to 1000ppm and flammable gases density from 100ppm to 10000ppm. MQ9 has an internal heater which starts warming up if a 5V voltage is applied. The internal resistance of this sensor changes as the density of the ...

MQ gas sensor Digital Read - Sensors - Arduino Forum

翻译 · 2021-5-6 · 17:19:21.742 → Digital MQ-6 PPM: 1. it looks like digital has a threshold on 65, above that is marking a logical 0. I tried switching cables on Voltmeter (I think I had them swapped). So now the results could be according with Arduino readings, giving 0.9v without gas, and -0.9 with gas.

MQ135 Arduino library | Details | Hackaday.io

翻译 · Hi Georg, I just did all the work: I attached an MQ135 to an external power and the Arduino Uno to the usb port. Than, I downloaded the library, I changed the RLOAD value to 1.0 (for my MQ135 board comes from aliexpress and has the 1 kohms RLOAD), I corrected the formula for get.Resistance as you indicated and the line #define ATMOCO2 410.92 with the current value I got from co2.earth.

LPG Sensor with MQ-6 and Arduino | Microcontroller Tutorials

翻译 · 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 ...
