摘　　要：针对目前温湿度记录仪存储记录有限、使用不方便等缺点,提出一种以STM32F103为核心,NTC、HS1101为温湿度传感器,TF卡为存储载体,LCD点阵等构成硬件;Fireware固件程序、FAT32文件系统及外设驱动构成软件系统,数据以txt文件存储的便携式海量温湿度记录仪方案。对系统软硬件实现进行了详细阐述,对存储量、精度等进行了估算、实现与校准。结果表明该方案具有海量存储、精度高、成本低、使用方便等优点。Refering to the shortcomings of the temperature and humidity recorder storage ,such as the restrictions, inconvenient to use, etc., this paper develops a plan achieveing a portable and mass recorder as follows： the STM32F103 as the core;high-precision NTC, HSll01 as the temperature and humidity sensor;TF card storage as the hardware; Fireware firmware together with the FAT32 file system and the Chinese Menus as the software; the ＊.txt file as the date storage. It describes the system software and hardware in detail, and also estiates ,implements and calibrates the amount of storage ,The precision and so on . The results show that the plan has a lot of advantages like massive storage, high precision, low cost, ease of use.
