摘要
设计以STM32单片机为本系统主控芯片的GSM远程温度检测系统设计,温度传感器DS18B20将采集的数据通过单总线传输给单片机,单片机进行简单计算得到实际温度值,并利用FSMC驱动LCD显示屏进行显示.当采集的温度超过预先设定的报警温度阈值时,STM32利用串口发送AT指令的方式驱动SIM800的GSM模块发送短消息至远程客户机手机上,实现远程温度测量和监视.该设计可以帮助人们完成一些复杂的环境温度测量和监控工作,节约人力成本,具有一定的实用性。
Based on the STM32 microcontroller as the main control chip of the system,a GSM remote temperature detection system is developed.In the established system,The temperature sensor DS18B20 transmits the collected data to Microcontroller through a single bus,then,the microcontroller performs simple calculations to obtain the actual temperature value,which is driven to display by the LCD display using the FSMC.When the collected temperature exceeds the preset alarm temperature threshold,the short messages are send to remote client mobile phone by the SIM800 GSM module,which is driven to use the serial port by the STM32 microcontroller.The temperature detection system can achieve remote temperature measurement and monitoring,and can also be used for saving labor costs,which can replace People to work in some complicated environmental temperature measurement and monitoring work.
