An ISM-Band Automated Irrigation System for Agriculture IoT

In this paper, an inexpensive and user-friendly agriculture automation system is proposed by networking a collection of sensors and actuators to sense the moisture content of the soil and control the water valves for multiple irrigation zones. Using freely available frequencies in the Industrial, Scientific, and Medical (ISM) bands, multiple sensors and actuators can be networked to communicate with one another without the need to pay for subscriptions to existing cellular networks. Each sensor and actuator connect to a central communication node which connects the end-user to the sensors and actuators through a cloud server. The proposed system can act as a base for large-scale smart agriculture deployments.
