Drip Irrigation System Based on Internet of Things (IoT) using Solar Panel Energy

Abstract

The limited availability of water on plantations at the top of the mountain becomes an obstacle when farmers want to irrigate the field. It makes farmers relying on dammed rainwater in rainfed areas. However, it has not solved the main problem because farmers need to make a proper use if their dammed water so that it could last the entire year. Thus, a new irrigation system technology is proposed. The purpose of this project is to design a drip irrigation system that could be controlled via Internet of Things (IoT) technology to raise the efficiency of water usage in plantations using solar panel energy. Design used in this drip irrigation system consists of hardware and software design, including system development. As for the method used here is IoT based. This drip irrigation system could monitor plant conditions in real-time. NodeMCU is used to send information and automatic valve controller with soil humidity as its parameter. With this tool, farmers are expected to be able to monitor soil humidity, pH and plantations conditions. Results show that soil humidity sensor has an average reading error of 0.364% and soil pH sensor has an average reading error of 0.378%. Solar panel testing shows that at 11:00 GMT the accumulator output reaches a maximum power of 8.821 Watts, while its standard output power is 480Wh. The battery can be full for 54.415 hours. The camera module can take pictures well. The drip irrigation system can run well when the humidity value is <70%.
