Arduino Uno Smoke Detector with MQ2 Gas Sensor - IoT Tech ...

· Their main objective is to detect potential fires, and ensure real time monitoring of indoor environment gases such as carbon monoxide (CO), LP gas, propane, alcohol, methane, and more. If you have access to an Arduino Uno board, you can tweak it to design your own homemade smoke detector. Adding a simple MQ2 gas detecting sensor module to the project makes it a combined smoke + gas detector ...

CO (Carbon Monoxide) Gas Sensor Using the Arduino Uno

· CO (Carbon Monoxide) Gas Sensor Using the Arduino Uno This simple project uses the Arduino Uno and the MQ7 Gas Sensor to sense the concentration of CO (Carbon Monoxide) in the air. The MQ7 requires a heater voltage that cycles between 5v (60s) and (90s), drawing approximately 150mA at 5v which exceeds the power capacity of the Uno, so I use the KA278RA05C adjustable …

Arduino CO Monitor Using MQ-7 Sensor : 8 Steps (with ...

After running sketch for at least 10 hours in clean air, take raw sensor value in the end of the measurement cycle, 2-3 seconds before heating phase starts, and write it into sensor_reading_clean_air variable (line 100). That's it. Program will estimate other sensor parameters, they won't be precise, but should be enough to distinguish between 10 and 100 ppm concentration.

How to Calibrate & Use MQ9 Gas Sensor w/ Arduino - Arduino ...

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 detectable gases changes. This value can be read by a ...
