基于特征值记录法的低功耗温度记录器

A temperature recorder with low power consumption based on typical values recording

给出了一种低价格、长时间、短记录间隔的环境温度记录器的设计方案．该方案采用PIC型单片机和EEPROM存储器，应用一种特殊记录算法，基于1min间隔记录平均值，可以无人自动记录1年以上的气象温度．另外，所用元件均选用达到工业温度（-40～85℃）标准的产品．

An ambient temperature recorder with low price, long period, and short sampling interval was introduced. With a PIC processor, EEPROM and a special recording algorithm, the period of one time recording can be more than one year, and the average temperature based on minutes can be got. The components in a recorder cost about 300 Chinese yuan, and the operating temperature for every component can reach the industrial standard （-40-85℃）.
