Gravity: Analog CO2 Gas Sensor | Arduino Official Store

Great and powerful sensor for everyone that wants to know the exact concentration of CO2 (Carbon Dioxide) in the air. This is the first CO2 sensor compatible with Arduino. The output voltage of the module falls as the concentration of the CO2 increases. The potentiometer onboard is designed to set the threshold of voltage.

For that reason, this CO2 sensor is designed by DFRobot engineer. This is the first CO2 sensor in Arduino market. The output voltage of the module falls as the concentration of the CO2 increases. The potentiometer onboard is designed to set the threshold of voltage. As long as the CO2 concentration is high enough (voltage is lower than threshold), a digital signal (ON/OFF) will be released.

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. A person ...

Gas Sensor - Arduino Project Hub

· I created this gas sensor because of multiple reasons: 1- I had to do a school project in which you use the Arduino Uno and upload it to the project hub. 2- I thought that the smoke sensor is a good project idea as it has the potential to save or help lives. 3- I had found how to make the code and I thought it very easy.

Arduino Gas Sensor - Project Guidance - Arduino Forum

· Worse still, just because the sensor is affected by CO, doesn't mean that other gases don't have an effect. So not only can you not distinguish between gasses using such a sensor, you're not even really sure that you're measuring CO - could be one of several others.
