STM32-based light, sound and touch three-control intelligent lighting
Abstract: In today’s society,the rapid economic development,people’s quality requirements for life continue to increase,and intelligence has become a trend in the development of science and technology. Intelligent lighting can be automatically extinguished during the day and lights up when someone passes by in the evening,and can control lighting by touch during the daytime or nighttime. It has the characteristics of low consumption,environmental protection,stability,stability,long life, and convenient life. This article mainly introduces the simple design and production of STM32 sound and light touch three-control intelligent lighting. This design mainly uses light- sensitive resistance sensors,voice- activated sensors,and touch sensors. The smoke sensor converts optical signals,sound signals,touch signals,and smoke signals into electrical signals, and amplifies and reshapes electrical signals,and then transmits the processed signals to STM32 single-chip microcomputer,accoring to the level of the signal level to determine the opening and closing of the relay,thereby controlling the light on and off. In the design process, Altium Designer software was used to design the circuit schematic, simulate the circuit, and test the circuit function.
