Abstract
In this paper, we study the temperature control system of thermoelectric cooler controlled by MSP430F149 microcomputer. The system achieves automatic temperature control by using PID algorithm and voltage-controlled steady flow circuit. Using the keyboard and LCD, we can set the temperature, display the working status and draw real-time temperature curve.
