Abstract

The design of a multi-channel temperature control system based three-wire measurement and USB 2.0 is described.The system uses platinum resistors as temperature sensor and a 24 bitAD chip AD7713 to convert temperature signal to digital signal

heating module outputs 4 channels of PWM signal and software is based on PID theory.The system can be used independently or used with a PC through the USB interface.
