Measure CO2 Levels With Ardunio and K30 Sensor : 9 Steps ...

+

27/01/2017· 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 300mA, and it won''t operate properly.
