Abstract

In this paper, a temperature control system based on micro controller unit is developed to obtain the operating temperature of the semiconductor laser by measuring and calculating the negative temperature coefficient thermistor through the microcontroller STM32F103ZET6, and then a direct proportional-integral-derivative (PID) algorithm is used to accurately control the preset operating temperature. According to the experimental verification obtained: this semiconductor laser temperature control system can accurately and efficiently control the working temperature at about 25 °C, floating range of ± 0.1 °C. Compared to similar products, this system demonstrates higher accuracy and extremely fast response rate in wide temperature environments.
