—A wireless sensor network (WSN) to automatically
irrigate the crops using soil moisture content values obtained
from the soil moisture sensor is designed. Gravity-feed drip
irrigation is actuated according to the needs of the crop by
using a relay to on a solenoid valve when the soil is dry, which
is determined by soil moisture content below 60%. End devices
communicate with the Coordinator via XBee communication
