GitHub stephanschulz/co2monitor: Arduino based CO2 ...

22/01/2021· CO2 monitor. Version of my homemade CO2 monitor uses the SCD30 sensor and multiple adafruit''s feather boards. Every 30 seconds data is logged on to an SDCard. With classrooms being a source of COVID19 outbreaks I wanted to make use of C02 level readings to gauge how well a classroom with 27 kids might be ventilated.


Measure CO2 Levels With Ardunio and K30 Sensor : 9 …

While the Arduino''s 5V power is theoretically able to power the K30, the sensor needs 300mA minimum to operate the light inside the sensor. The problem is, if you power the Arduino from your PC''s USB port, the K30 has to share power with the Arduino, your mouse, and any other devices on the USB bus. The power to the sensor will drop under ...
