Digital output D0

Using the potentiometer plate on the back of the unit, a threshold is set, after which output D0 switches from high to low. Output D0 can be connected directly to a microcontroller or starter kit including Arduinoor e.g. toa buzzer modulethat willsignal too low or high ozone level in the air.

Analogue output A0

The sensor also has an analog output A0, which should be connected to the A/C converter output (analog input in Arduino). This will allow measuring the proportional voltage signal to determine the concentration more precisely.
