Connect soil humidity sensor with Arduino board for analog read
How it's done
Soil humidity sensor can be used as analog and digital sensor.
In these next few steps we will use it as an analog sensor and then we will show how to use it as a digital sensor.
On sensor board there are four pins: Vcc, GND, D0 and A0.
Connect three female side wires pins with sensor male pins (Vcc - white, GND - black and A0 - brown) as on the picture.
Connect three male side wires pins with Arduino board (5V - white, GND - black and A0 - brown) as on the picture.
Wire coloring is not important, it is used for easier referencing.
