Arduino Guide for MQ2 Gas and Smoke Sensor -

05/02/2021· The MQ-2 Gas sensor can detect or measure gasses like LPG, Smoke, Alcohol, Propane, Hydrogen, Carbon Monoxide (CO) and even Methane concentrations anywhere from 200 to 10000ppm. The module version of this sensor comes with a Digital Pin which makes this sensor to operate even without a microcontroller and that comes in handy when you are only trying to detect one particular …

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 really would have no idea that they are breathing ...

Precalibrated CO2 sensor - Sensors - Arduino Forum

06/05/2021· Could you point me on some calibrated and easy to use CO2 sensor, preferably with some digital interface for long distance reading? What I'm trying to do is to make cheap device that measures temperature, humidity and CO2 (air quality) on 3 points in an apartment with just one Arduino. For temp/humidity I'm thinking to use DHT22, nice, cheap and 1-wire sensor (for up to 20m distance).

Carbon Monoxide Gas Sensor MQ-7 - Arduino Project Hub

I had previously published a project with an MQ sensor and received a lot of critical feedback on it. Today I also expect your feedback, but only of a positive nature: with the MQ-7 carbon monoxide gas sensor and the matching PCB from Pololu, analog measurement using the ADC from the Arduino is no longer a problem.
