Soil Moisture Sensor Hookup Guide Using a digital pin set to HIGH on an Arduino, for example, is an easy way to accomplish this. If you wish to power the sensor with more than a digital pin on your microcontroller can provide, you could always use a transistor. Assembly.

Adafruit TSL2561 Digital Luminosity/Lux/Light Sensor

Digital Mode – Interfacing Arduino and Soil Moisture Sensor. To connect the soil moisture sensor FC-28 in the digital mode, we will connect the digital output of the sensor to the digital pin of the Arduino. The Sensor module contains a potentiometer with it, which is used to set the threshold value.
