Design of Timing Socket Based on Single Chip Microcomputer

In this paper, the design of timing socket is mainly used for smart timing control of household appliances, and the working time of timing is set by pressing the key. In the working period, the external connection device and the power supply are in the conduction state. Outside the set time period, the external connector is disconnected from the power supply. This design uses STC89C52 as the driving chip. DS1302 clock module provides accurate timing. LCD1602 LCD module displays time and operation interface. The relay module controls the connection between the socket and the power supply. DC power supply module is converted to DC power supply module.
