Soil Moisture Content Detector

A system to detect the soil moisture content has been developed. The
detector uses probes as a sensing element to detect the moisture of the soil. The
output of the device is represented as digital using microcontroller. The detector is
designed based on concept of electrolysis and resistance method. The resistance of
soil is increased inversely proportional with decreasing of the amount of water in
soil. Furthermore, the device will be practical to use and affordable.
