Water through the heating circuit of the electrically heated, and the temperature of the water is sampled, sampled signal by the DS18B20 will digital quantity fed to the microcontroller system, after computer processing, combining the keyboard control for LCD1602 display, and to achieve the control on the temperature of the water and more than the water temperature alarm system. Microcontroller control Kettle hardware configuration including the 8051, LM393 chip microcontroller control circuit, temperature detection circuit, keyboard and display circuit and temperature heating circuit. Key circuit of the entire system is the SCM control circuit, and signals the completion of the conversion of the input and output, the input signal can be sampled by the temperature detection circuit by the temperature sensor for processing processing output to the display to display, and the temperature can be controlled by the controller, exceeds the specified temperature when the water was heated at the same time, the buzzer alarm, and when the water temperature is below the set temperature value, the system began to run on its own, another Kettle control system can prevent dry [15].
