Design and implementation of a multi-functional desk lamp with intelligent posture correction based on MCU

Abstract

With the improvement of people's living standards, more and more people have become accustomed to sitting in front of computers for long periods of time for work or study, which can lead to poor sitting posture habits. This paper aims to design an intelligent desk lamp that combines Bluetooth technology with remote communication technology to improve people's quality of life by correcting sitting posture and providing comfortable lighting experiences. The design uses the STC89C52 as the main control chip, and combines infrared sensing, photoresistor, and Bluetooth HC05 remote communication to detect and control parameters such as human sitting posture and ambient light. Experimental results show that the intelligent desk lamp designed in this paper has excellent lighting effects and can adjust brightness adaptively. In terms of sitting posture correction, the desk lamp can accurately detect human sitting posture and remind users to adjust their posture in a timely manner. In addition, the Bluetooth HC05 remote communication module enables communication with mobile phones and other devices, and facilitates remote control through sending specific AT commands or defining specific communication protocols. The intelligent desk lamp designed in this paper not only improves the comfort and productivity of office environments, but also provides a useful application of smart home technology in daily life. In the future, with the increasing demand for smart home technology, the market prospects of intelligent desk lamps, especially those with remote communication functions, will become even broader.
