为了实现远程传输,让用户实时的监测环境,本文介绍了一种基于GSM无线传输技术的温湿度检测装置的实现方法。系统使用STM32F407和SIM900A为主要部件,温湿度数据使用短信或者电话通知用户。文章介绍了相关的AT指令、驱动函数等,而且具有良好研究价值。
In order to achieve remote transmission, allowing users to monitor the environment in real time, this paper describes a method based on GSM wireless transmission technology temperature and humidity detection device. System uses STM32F407 and SIM900A as the main components, temperature and humidity data using SMS or telephone to inform the user. The article introduces the relevant AT commands, driver functions, etc., but also has good research value.
