Design of intelligent water dispenser controller based on single chip microcomputer

This paper introduces the design of an intelligent water heater with AT89S5 1 as the main control device and DS 18B20 as the temperature sensor. Its hardware circuit includes main controller, keyboard circuit, temperature measuring circuit, LCD 160 display circuit and DS 1302 factual clock circuit. A water temperature control system for drinking machine is designed. When the temperature reaches the set insulation temperature, the heating is automatically stopped, and when the temperature is lower than the set lower limit temperature, the heating is automatically started. It achieves the effect of automatic control and intelligence, with simple circuit hardware design and low cost. At the same time, you can set the start and end time of the work.
