CO2 Gas Sensor | Raspberry Pi Arduino Critics Corporation

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. It ...

Building a CO₂ Monitor with Python on a Raspberry Pi ...

Making it work on a Raspberry Pi. My ultimate goal was to make a liveplot that people can check throughout the day to see the CO 2 concentration over time, making it easier to spot when the air is getting stuffy. That means I can’t just attach the meter to my laptop while I’m around RC, it needs to be running 24 hours a day in some outoftheway spot. Thankfully the Recurse Center is lousy with Raspberry Pis …
