The goal of this project was to create an automatic irrigation system for plants. Plants are beneficial to have indoors. In addition to their airpurifying properties, they have been shown to increase employee productivity and decrease sick leave at workplaces. This paper deals with an automatic irrigation system which automatically senses the moisture content of soil and decides whether irrigation is needed or not and how much water is needed for soil. We used a UV sensor for the proper amount of sunlight and a PH sensor for maintaining the Ph value for homegrown plants. The final design consisted of a microcontroller (Arduino UNO) which controlled the system, moisture sensor, temperature sensor, UV sensor and PH sensor. The project resulted in a system that managed to keep the plant alive. Instead of batteries, solar cells could be used to meet the system's energy needs. The Automated Plant Irrigation system represents our most basic step towards automated farming drought and loss due to irrigation issues.
