摘要
针对现有温湿度记录仪数据存储方式实现复杂、功耗大等缺点,提出了一种基于SD卡存储的便携式温湿度记录仪的实现方案。对整个系统的软硬件实现进行了详细阐述,同时对系统功耗进行了估算及测试。该记录仪可以将数据转存到SD卡中以便在PC端进行分析处理,研究结果表明该方案具有功耗低、实现简单、成本小等优点。
Aiming at solving the problems of complicated storage and big power consumption, the implementation scheme of portable temperature-humidity recorder based on SD card was proposed. The realization of integrated design was illustrated in detail. At last, power consumption of the system was estimated and tested. In the system, SD card was applied to store the data, which is convenient for PC processing. The results indicate that the scheme is simpler, cheaper and lower power consumption.
