CO (Carbon Monoxide) Gas Sensor Using the Arduino Uno

2014-03-29· 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 …

Create Your Own CO Detector - Digi-Key

Building a CO (carbon monoxide) detector that can alert you to dangerous levels of CO can be done with as little as a gas sensor, an Arduino (or other microcontroller) and some resistors. Adding a few op-amps can boost the sensitivity to measure the amount of CO present in the environment. Expanding on this knowledge, you can build your own air quality monitoring station, and compare your own ...
