I am new at this so this might be an obvious question.
I have an AirQuality Sensor that I would like to connect to an Arduino Uno. Unfortunately I dont have the brick , I need to connect the 4 cables coming out of the sensor directly to the Arduino board.
Does anybody have any suggestions how to connect the cables? I presume that the red should go to the 5v pin and the black should go to gnd, but what about the yellow and the white? What pins should they go into?
Also, any suggestions as to how to access in an Arduino sketch the values for CO2, CO Methane and Alcohol?
