Intelligent learning lamp design based on stm32
Abstract: This paper designed a set of intelligent learning lamp system based on stm32, the intelligent system through the human body infrared sensor detects whether desk lamp beside someone, reuse the ADC module to sampled signal transformation, so as to control and adjust the switch of desk lamp, brightness resistance testing of indoor light intensity to adjust the LED brightness, when ultrasonic sensor module testing to the human body and the distance from the desk close buzzer alarm, LCD display brightness. This system consists of two parts, hardware and software, the hardware part mainly includes the stm32, SR04 ultrasonic sensor, a buzzer module, oled LCD, brightness sensor, ADC0832 module, body induction module and power module, software part mainly includes the general control program and each module control. Experimental results show: this system has stronger applicability, easy to use, further verify the effectiveness of the design in this paper.
