It is hold by STC company produces the 8-bit microcontroller STC90C516RD + as the core; DS18B20 as temperature sensor, used for real-time measurement of the temperature of the food in the microwave oven; Independent type keyboard adjust input, which is used to set the work parameters such as temperature, time time; Use 1602 LCD screen to display the time and temperature. Through this design can realize the intelligent control of the microwave oven, microwave oven is the application of function more powerful, easy to use. Single chip microcomputer minimum system STC90C516RD + as the core, and the clock and reset circuit, the circuit structure is simple, strong anti-interference ability, relatively low cost, very accord with all requirements of this design.
