Design of Intelligent Water Heater Control System
Abstract:This article is mainly based on MCU AT89S52 intelligent heater control system design. Hardware part of the main microcontroller determinant are keyboard, monitor LCD1602, DS18B20 temperature sensor, buzzer alarm circuit, electric heating module. Through the temperature sensor DS18B20 collecting temperature and the temperature in the LCD1602 display, keypad set the temperature, the heating temperature control can be achieved. Using C language programming to achieve it with intelligent heating automatically detect the water temperature. Software debugging is correct, and Keil joint commissioning with Protues and simulation run successfully. By welding components, debugging hardware circuit ,the function is proper and can basically achieve intelligent control of the functions. This design of electric water heater is functional and practical and simple. Using MCU can improved system stability and accuracy.
