Abstract: In this article, the classroom lighting control method and control mode, especially the present development of the
classroom light intelligent control, are discussed in detail. Furthermore, the classroom light intelligent control principle and the
realization method are discussed, the design idea of the classroom light intelligent control system based on embedded system 1s
put forward in an innovative way, and on this basis, the hardware device and the corresponding software program of inteligent
control system are designed In this system, STM32 is applied to be the intelligent component of the control device and infrared
human body detect sensor is adopted to detected the existence of the human body and circuit containing light photosensitive triode
used to detect environmental light intensity. According to the rational conditions of switching light on or off, the embedded
classroom lighting system is orderly and intelligently controlled to avoid a large amount of waste of electricity in classroom based
on identifying the signal of the existence of human body and the signal of the environmental light. In addition, this system has a
variety of alarm functions. The software is programmed in C language and designed in common modularization with high clarity
and good portability, so this software is easy to improve and expand. This system has many advantages-small in size, easy to
control, high reliability, strong specificity, reasonable price and so on, so it can meet the requirements on classroom light
control of many colleges in theory and achieve energy saving purpose to a large extent in most cases
