Soil Moisture Content Detector
Ab Karim, Alia Dawina · 2011
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.
