Abstract

Background/Objectives: This paper presents an automatic irrigation system to provide water to the farms based on soil and temperature conditions using an android application, WSN and GPRS modules. Methods/statistical Analysis: An algorithm is developed such that soil moisture sensor and temperature sensor values are continuously fed to Arduino UNO micro controller. The sensor information is compared with the threshold values and based on that, decision will be taken to water the crops. The system is equipped with the photovoltaic panels and dual communication is established based on cellular-internet interface for continuous inquiry of data by the user. We have also developed an android mobile application for intercepting the data generated. For that purpose, we can also employ a web site. Findings: Because of system’s energy sovereignty, low cost and relatively more amounts of underground water saving, this system is preferable at water scarcity locations like desert areas. Conclusion: This irrigation system has been working with high efficiency and top speed. This system sends message to the user whenever sensors exceed there threshold value, by this system every user can understand the soil conditions and controls the system too manually, if needed.
