Calibration Parameters

With the method of artificial soil columns, several kinds of soil, such as, loam, clay, and sandy soil were used for FDR (frequency domain reflectometry) moisture sensor calibration experiment. Then, these data showed that the frequency of soil moisture sensor is monotone decreasing with the increase of soil volumetric water content, so the correlation is obvious. Different kinds of soil affected moisture sensor parameter remarkably. A better result would be obtained in classification calibration than that in concentration calibration. This experimental result had a great meaning for fine calibration of soil water automatic detector in the areas with complex kinds of soil.

Working Principle

The Indonesian country which is famous for its tropical climate has now experienced a shift in two seasons (dry season and rainy season). This has an impact on cropping and harvesting systems among farmers. In large scale this is very influential considering that farmers in Indonesia are stilldependent on rainfall which results in soil moisture. Some types of plants that are very dependent on soil moisture will greatly require rainfall or water for growth and development. Through this research, researchers tried to make a prototype application for watering plants using ATMEGA328 microcontroller based soil moisture sensor. Development of application systems using the prototype method as a simple method which is the first step and can be developed again for large scale. The working principle of this prototype is simply that when soil moisture reaches a certainthreshold (above 56%) then the system will work by activating the watering system, if it is below 56% the system does not work or in other words soil moisture is considered sufficient for certain plant needs.
