The digital output D0

With the help of the potentiometer placed on the reverse side of the board, set is the threshold above which the output D0 is changed from a high to a low status. The output D0 can be linked directly witha microcontrolleror commissioning set, includingArduino, or for example, with a module of a buzzer which will signal too low or high level of gasesin the air.


Analog output A0

The sensor has an analog output A0 which must be connected to the pin of the converter A/D (of analog input inArduino). This will allow you to measure the proportional voltage signal and more accurately determine the concentration.
