Energy-Saving System Designed with Combining Ultrasonic Position and ZigBee Wireless Net Work

Abstract

In this paper, the first time energy-saving system implemented with the design of combining ultrasonic position system with Zigbee wireless net work. There were some studies about Zigbee wireless networking and ultrasonic positioning respectively instead of combining the two systems in unique system to accomplish a task together. The study adapted ultrasonic positioning function to correctly detect both people’s position and the number of them in a living space, and then send the information to servo computer through Zigbee wireless sensor net work as a data by which the control microprocessor would dynamically computer controlling signals to control related circuits on power-consumption facilities in living space so as to save energy consumed by facilities. After real experiment in a certain designed living space, the system was proved successfully control lights and air-conditioning facilities in order to get to the goal of energy-saving.
