Wireless communication technology has been widely used in various fields of work, management, communication and education. The development of wireless communication technology has improved the quality of life of people, thus continuously promoting the development and progress of society. As a new short-range wireless communication technology, ZigBee technology has low power consumption and low data transmission rate.

Today, ZigBee technology has been widely used in the fields of industrial control, smart home and consumer electronics. European and American countries have introduced consumer ZigBee products. Compared with foreign countries, ZigBee technology started late in our country, and has not been paid much attention by researchers and enterprises until recent years. However, the domestic ZigBee technology is developing rapidly, drawing on the mature ZigBee technology achievements and experiences of foreign countries. Attracting more and more universities and enterprises to join in the research of ZigBee technology, ZigBee technology has become one of the research hotspots in domestic wireless communication technology.
