基于nRF905的无线环境监控系统设计

温度、湿度和烟雾度作为最基本的环境参数,它们的测量方法和装置对现实生活和生产具有重要意义.通过利用无线通信模块nRF905和微处理器STC12C5A08AD设计了无线环境监控系统,主要包括数据采集子系统和数据接收监控子系统.数据采集子系统由数字传感器DS18B20构成的温度测试单元,数字传感器DHT11构成的湿度测试单元及模拟传感器MQ-2构成的烟雾度测试单元组成,通过单片机STC12C5A08AD分别对温度、湿度和烟雾度采集处理;然后通过无线通信模块nRF905构成的通信主体单元传输到数据接收监控子系统,实现对环境的实时监控.

Design of Wireless Environmental Monitoring System Based on nRF905

Temperature,humidity,and smoke degree are the most basic environmental parameters, and their measurement methods and apparatus are of great significance for the real life and production.A wireless environmental monitoring system is designed by using wireless communication module nRF905 and microprocessor STC12C5A08AD.The system includes a data acquisition sub-system and a data reception and monitoring subsystem.The data acquisition subsystem consists of a temperature test unit of digital sensor DS18B20,a humidity test unit of digital sensor DHT11 and a smoke degree test unit of analog sensor MQ-2.The temperature,humidity and smoke degree are collected and processed by microcontroller STC12C5A08AD,then they are transferred to the data receiving monitoring subsystem by main communication unit of a wireless communication module nRF905 to achieve the real-time monitoring of the environment.
