Design of Wireless Temperature and Humidity Monitoring System Based on STM32W108

针对传统的温湿检测系统的繁琐、不便携的特点,本文设计了一款无线通讯的温湿度监测系统。该系统采用高新能、低功耗、集成度高的STM32W108为系统的主控芯片,集成了32位contex-M3微处理器和2.4GHZ的收发器,采用双电源切换供电。通过DHT11温湿度采集芯片能够准确的采集环境温湿度,作出相应的报警反馈,并通过无线传输的方式将采集的数据发送给接收模块。经过实验测试,该系统能够准确快速的检测环境的温湿度,响应时间在4.5ms左右,具有一定的应用价值。

Aiming at the tedious and inconvenient characterististics of the traditional temperature and humidity detection system,this paper designes a model of temperature and humidity monitoring system for wireless communication.The system uses STM32W108 for the system of master control chip,which is high energy,low power consumption and high integration.It Integrates Contex-M3 32-bit microprocessor and 2.4 GHZ transceiver,and adopts double power switching power supply.By DHT11 temperature and humidity acquisition chip,it can collect accurate environmental temperature and humidity,make corresponding alarm feedback,and be collected by means of wireless transmission of data sent to the receiving module.After experiments and testing,the system can accurately fast test environment temperature and humidity,it responses time at about 4.5 ms and has a certain application value.
