Abstract

This study is an examination about soil moisture level based on an automated watering system for a small plant nursery. The soil moisture sensors sense the current soil moisture level and send a notification to the user if the current soil moisture level is below than the required soil moisture level. Then the user should select the plant which requires watering, and then it displays the current soil moisture level and the required soil moisture level. To start watering automatically, the user must switch on the motor from the mobile application, and if not, he gets a notification to turn on the motor. The motor can be switched off by either from the mobile application or it turns off automatically. The main aim of this project is to develop a wireless smart irrigation system to provide irrigation which is automatic for the plants, which help in saving money and water in return. The main objective is applying the system for improvement of the fertility of the soil and the plant. The project aspires to defeat the challenges addressed above. The whole system is micro control based and can be operated from a remote location through wireless transmission. Hence there is no need to be concerned about the overflowing of water in the process of watering. In Sri Lanka, agriculture plays a vital role in the production of food crops and the economy. In our country, agriculture depends on monsoons which are not an adequate source of water. Therefore, the irrigation methods are used in the agricultural arena. Internet of things (IoT) is a turning point in the interpretation of technology. IoT represents an important role in many fields, one of which is agriculture by which responsible authorities are able to feed almost all the people on the earth in the millennium.
