基于HOLTEKMCU的考勤及控灯系统

针对学校普遍存在的考勤制度难以得到有效落实的现状，及目前使用的灯控系统存在的各种问题，本设计基于单片机HOLTEKMCU，结合光电开关、光敏传感器等元器件，实现了自动考勤、智能控灯、空位数显示等功能。利用键盘输入法解决了教室规格大小不统一的问题。本设计通用性强，应用范围广，可扩展性好。若将其与网络连接，可实现教室座位利用率的查询等。

Attendance Check and Light Control System Based on HOLTEK MCU

With view to the difficulty of attendance system implementation and problems existing in light control system, the design, based on single-chip HOLTEK MCU, combined with photoelectric switches, light sensors and other components, has the functions such as automatic attendance check, intelligence light control and display for the attendance. With its universality, the design takes full account of different sizes of the classrooms, and offer the proposal of using keyboard input to control the sizes of the classrooms. By connecting it with the computer we can achieve the inquiry functions of the classroom using through the network.
