Automated Control Systems for Smart Farm

Abstract

     Presently, there are many forms of agricultural cultivation, but an important factor in agricultural cultivation is the watering of various vegetables. Traditional watering either manual or sprinkler system without control causing the uneven watering makes area flood and vegetables receive water more than necessary. The researchers therefore design an automatic watering system for vegetable plots through soil moisture sensors. The automatic watering system transmits the data, soil moisture, back to the receiver using a microcontroller (Arduino board) to control the watering system. There are 2 simulated planting plots for collecting and analyzing data. The measurement value is then sent through a wired communication module to the microcontroller for processing whether water should be supplied or not. By passing the conditions of 70% humidity to control the water supply system for watering, if the humidity is below 70%, the system will supply water automatically to the vegetable plot. And, when the humidity is more than 70%, the system will stop supplying water. The measured moisture value will be sent to the SD card module for analyzing. The test results show that the built system is able to control soil moisture the best at 69.99% with an error of 0.000948% and a standard deviation of 1.04.
