How does an NDIR CO2 Sensor Work? |

Serial output is especially useful for using NDIR CO2 sensors with Arduino or Raspberry Pi microcontrollers. Early CO2 measurement devices. Since Joseph Black, a Scottish chemist and physician first identified carbon dioxide in the 1750s, scientists have looked for a way to measure this common gas. One of the earliest CO2 measurement devices was a mercury manometer. Manometers use a U …

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 out-of-the-way spot. Thankfully the Recurse Center is lousy with Raspberry Pis …
