In this paper, a wireless sensor network (WSN) is constructed to carry out certain applications. This WSN is composed of a sensor, monitor, controller, etc. It has the benefits of low cost and low power consumption. A WSN can be used in many applications in a range of different control technologies, such as temperature monitoring. ZigBee is used to test the performance of the WSN. The experimental results reveal that the design requirement can be achieved; they also demonstrate that the WSN control methodology allows good performance of data transfer using a liquid crystal display (LCD) and motor control.
