With the advent of Internet of Things time, more and more applications require location-based services. This article
describes the concept and basic principles of several of Internet of things positioning technology such as GPS positioning,
Base Station positioning, ZigBee positioning. And then the advantages and disadvantages of these types of positioning
technologies are compared.
By analysis of the low degree of intelligence of the traditional lighting control methods, the paper uses the singlechip
microcomputer for the control core, and uses a pyroelectric infrared technology to detect the existence of the human
body, light sensors to sense the light intensity; the interface uses infrared sensor module, photosensitive sensor module,
relay module to transmit the signal, which based on ZigBee wireless network. The main function of the design is to
realize that the lighting can intelligently adjust the brightness according to the indoor light intensity when people in door,
and it can turn off the light when people left. The circuit and program design of this system is flexible, and the system
achieves the effect of intelligent energy saving control.
