why we used MCP3008? i saw mq135 sensor have already digital pin why we cannot direct digital pin. Reply. Veli 2212019 at 18:30. That digital pin is not a serial communication pin. On the sensor’s circuit board, there is a potentiometer setting a threshold value. If analog output is above that threshold value, digital output becomes high.
