基于STM32的便携式海量温湿度记录仪设计

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。

Design of portable temperature and humidity recorder based on STM32

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-pre cision NTC,HS1101 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.
