New temperature control system with touch screen and digital temperature sensor. Single chip microcomputer is used as the control core. The digital temperature sensor is the measuring element, and the solid-state relay is the executive element. Through the PID control algorithm, the temperature control of the object is realized. The touch screen is used as the man-machine interface to set and display the temperature value, which simplifies the circuit structure and improves the reliability of the system.
