Accurate self-calibrating CO2 meter -

Jun 28, 2021· As a project at the University college of Odisee Energietechnologie (Belgium) we made 8 CO2 meters that indicate the quality of air and measure CO2. The meter uses an IR-sensor, UNO, LCD and battery pack and auto-calibrates itself (each 24 hours or shorter). With the link you'll find the code and a description of the hardware. We made a short documentation so that you have an idea about …

Dissolved CO2 sensor - Sensors - Arduino Forum

May 06, 2021· Dissolved CO2 sensor. system October 22, 2012, 7:21pm #1. I’m looking to build a sensor for an algae project which reads out the dissolved CO2 content of the algae tanks. This is not easy because the water is opaque and mucky, it’s dissolved, not gaseous CO2, and since the pH is not constant in algae tanks, one cannot use a pH calculation ...

CO2 Monitoring As an Anti-Covid19 Measure -

It is generally recommended that indoor CO2 sensors be placed at a height between 1 and meters, away from doors and windows. With such a small size, the visual clues informing the user of an excess CO2 concentration ( the LED turning red and the ppm figure exceeding the chosen threshold) are relatively discreet.
