Description: This design uses no ROM 8051 as the main control chip. The interface circuit 8051 8155,2732 and ADC0809 and other chips. 8155 for the keyboard/LED display interface 2732 can be used as an external ROM memory 8031, ADC0809 for the temperature measurement circuit input. The temperature control circuit is designed by SCR Power Regulator to achieve. Triac tube and heating wire connected in series in the AC 220V, 50HZ AC power circuit, in a given period, as long as the change in SCR 8031 on-time control of the power of heating wire can be changed in order to achieve the purpose of regulating the temperature .
