Design and Implementation of Soil Moisture Monitoring and Irrigation System based on ARM and IoT

Abstract

This paper proposed a novel framework for soil humidity control and watering management based on the Internet of Things (IoT) and ARM. The framework is designed to minimize manual field process and transfer information to a cloud server that is accessible through a web application. The proposed scheme has advantages in reducing costs, restricting water waste as well as minimizing the physical interference. It also advocates low maintenance and environmentally sustainable irrigation. The sound, humidity and temperature sensors are combined with ARM single board computer (called the Raspberry Pi). A relay module is placed to regulate the stream of water. The sensor obtained values are stored on the cloud server and the necessary values and recommendation are provided via the web application. When the ground temperature is high and soil humidity is low, the automatic irrigation system is triggered and user notification can be performed with email. The model showed expected impacts at the various levels of humidity.
