Smart irrigation system with an Android-based remote logging and control

In order to eliminate the drudgery associated with irrigation practice, a smart irrigation system with an Android-based mobile application and control system is developed and tested under the local and cloud server architectures. The system uses four sensors (moisture content, temperature, humidity and ultrasonic) to acquire real-time data from the irrigation site which are fed to the central controller. Wi-Fi device is used to provide Internet connectivity to a local and cloud server. A mobile application is developed to display the four sensor measurements on a user-friendly graphically interface in real-time as received from the server. The system automatically starts/stop irrigation pumps based on measurements received from the soil moisture content sensor after attaining certain threshold values. Its remote logging capability makes it possible for users to view on their mobile phone the status of their farmland such as atmospheric temperature, humidity, level of water in the reservoir and soil moisture content from any location, provided Internet access is available. It also gives the user the flexibility of starting a pump on the farmland remotely using his mobile device. Experimental results reveal that the local server is more stable than the cloud server architecture.
