Automatic Irrigation System Using Wireless Sensor Network

An automatic irrigation system was developed to optimize water uses for agricultural crops. The main objective is to provide an energy efficient algorithm for wireless sensor network used in irrigation system to minimize power consumption. Communication between the sensor nodes and the data receiver is done via Zigbee protocol. Internet link allows supervision through mobile telecommunication devices, such as a Smartphone. The irrigation system can be adjusted to a variety of specific crop needs and requires minimum maintenance. The system has a distributed wireless network of soil-moisture and temperature sensors placed in the root zone of the plants to detect the water level and temperature respectively. This work describes details of the design and instrumentation of variable rate irrigation, a wireless sensor network, and software for real-time in-field sensing and control of a site-specific precision linear-move irrigation system. This work also introduces the Soil moisture collection in a Precision Irrigation System using the new platform, named DZ50, which is based on the ATmega328P micro-controller and the RFM12b transceiver, and consumes very low energy in low-power mode.
