Is anyone here had an experience in order to build Soil Moisture Sensor?
Actually my project is about to detect the soil moisture by using Vegetronix VG400 Soil Moisture Sensor probes.
If the moisture too dry (RED LED blinking), if the moisture wet (GREEN LED blinking) and if the condition of the soil is not too dry and wet (YELLOW LED blinking).
I also wanna make an alarm when the moisture too dry.
Can somebody help me to figure it.
Is there any link which I can refer to?
