16/03/2018· MQ137 Pin Configuration. You can also use this sensor to get digital output from this pin, by setting a threshold value using the potentiometer. This pin outputs 05V analog voltage based on the intensity of the gas. Out of the two H pins, one pin is connected to supply and the other to ground.
01/05/2017· Successivamente con questi valori può leggere la resistenza del sensore, inizialmente con un multimetro, e poi utilizzare il valore letto per validare i coefficienti trovati. Come può vedere dal grafico, il sensore MQ135 rileva benzene (C6H6) da 10ppm a 200ppm circa. Sotto i 10ppm è fuori specifica datasheet, potrebbe leggere un valore, ma rimane comunque fuori dalle specifiche. Cordiali ...
