MQ-7 Carbon Monoxide (CO) Gas Sensor Module - South Africa ...

Use the MQ7 module with your Arduino to easily detect Carbon Monoxide (CO) gas. Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that is slightly less dense than air. It is toxic to hemoglobic animals (both invertebrate and vertebrate, including humans) when encountered in concentrations above about 35 ;ppm, although it is also produced in normal animal metabolism in low ...

CO (Carbon Monoxide) Gas Sensor Using the Arduino Uno

Mar 29, 2014 · 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 1.4v (90s), drawing approximately 150mA at 5v which exceeds the power capacity of the Uno, so I use the KA278RA05C adjustable voltage regulator to drive ...

MQ-7 CO Module Setup - Sensors - Arduino Forum

11-02-2017 · You wire that module right to your Arduino, all needed components are on the module. Here is a tutorial for that family of sensors,use the AOUT pin on the MQ-7 module. The trim cap is for adjusting DOUT. Accurate calibration is difficult at home, the datasheet tells you to allow the module to pre-heat "No Less Than 48 Hours".

MQ-7 Carbon Monoxide Sensor Circuit Built with an Arduino

In this project, we will go over how to build a carbon monoxide sensor circuit with an arduino. The carbon monoxide sensor we will use is the MQ-7 sensor. This is a sensor that is sensitive to effects of CO. Carbon monoxide (CO) is a very dangerous gas which is odorless, colorless, and tasteless, so it cannot be smelt, seen, or tasted.
