IOT Based Smart Irrigation System Using Solar Energy

Abstract

Many people around the world depend on agriculture, as it is the main source of food. With the advancement of science, many techniques have spread that work well on agricultural production. Therefore, the smart irrigation system is a modern technology that contribute to monitoring the condition of the fields.

IOT Based Smart Irrigation System Using Solar Energy can give as many advantages such as real time feedback and this system can save us time and effort[1,2].

The ESP32 is an affordable and energy-efficient series of microcontrollers that operate as system-on-a-chip (SoC). These microcontrollers come equipped with integrated Wi-Fi and capabilities, offering a highly integrated structure for diverse applications. Because of the hard environment in Saudi Arabia and lack of the rain in most of the regions and the limited water sources it’s hard to farm and maintain the plants or plant all the cities the entire year, also the distance between agricultural areas and residential areas.

On this paper we design and implement an IOT based smart irrigation system using solar energy to achieve many goals like: raising the efficiency of agriculture, treating water scarcity, making farming easy and simple, and using clean energy. This system collects data from wireless sensors measuring soil moisture using IOT and controls the irrigation pumps. The pumps are monitored and protected using sensors. Also, the whole system is monitored and protected from human’s or animals’ attacks using motion sensor. The system is powered using solar energy system using lithium-ion battery and Pulse Width Modulation (PWM) battery charger. Finally, a mobile application is designed and implemented for monitoring the condition of the system and controlling its components.
