Automatic Irrigation System on Sensing Soil Moisture Content

Abstract

Abstract

In developing countries like Bangladesh, farmers depend on rivers and rainfall to water their crops properly. Even though water pumps are used for irrigation purposes, the farmers have to operate those manually. In this paper, a system is proposed to reduce the human intervention as it will switch the motor on/off automatically after sensing the soil moisture content. Further system will allow the farmers to receive much needed rest and also stop the wastage of water due to the motor being on for too long. In order to ensure that the amount of water added is accurate a performance analysis was done to ensure that the moisture percentage shown by the sensor was reliable. Experiment was successfully done for different types of crops where different levels of irrigation are required. The system also shows the percentage of moisture present in the soil. In addition, every time the motor is turned on or off, automatically a notification will be send to the farmers’ cell phone
