现代信息技术的三大基础是信息采集(即传感器技术)、信息传输(通信技术)和信息处理(计算机技术)。传感器属于信息技术的前沿尖端产品,尤其是温度传感器被广泛用于工农业生产、科学研究和生活等领域,数量高居各种传感器之首。近百年来,温度传感器的发展大致经历了以下三个阶段: The three foundations of modern information technology are information gathering (sensor technology), information transmission (communication technology) and information processing (computer technology). Sensors belong to cutting-edge information technology products, especially the temperature sensor is widely used in industrial and agricultural production, scientific research and life and other fields, the highest number of sensors in the first. Over the past 100 years, the development of temperature sensors generally experienced the following three stages:
