Arduino CO2 Meter

How to make a benchtop CO2 meter.

In this project, we will be making a benchtop-style CO2 meter using the sensor from Atlas Scientific hooked up to an Arduino Uno. The real-time readings in PPM will be shown on a liquid crystal display (LCD). Both the sensor and display are connected to the Arduino via I2C.


This device was developed and tested using a Windows computer. It was not tested on Mac.
The CO2 sensor is for gaseous CO2 only. Do not submerge!
The meter is not waterproof.”
