基于nRF24L01智能环境监测系统设计

Design of Intelligent Environment Monitoring System Based on nRF24L01

本文是基于短距离无线收发nRF24L01芯片,温湿度传感器DHT11以及单片数字照度传感器BH1750模块,以低功耗、通用性强的单片机STC89C52为微控制器,设计的一套满足实际应用需求的无线传感器网络环境监测系统。实践证明,该系统能对室内环境进行实时监测,而且只需对终端节点进行扩展就可应用于不同场合,相对于传统常规有线传感器监测系统和已有的无线传感器网络监测系统具有成本低、易布置、扩展性强、低功耗等优点,具有较高的实用价值。

This paper is based on the short distance wireless transceiver chip nRF24L01, temperature and humidity sensor DHTI 1 and single chip digital luminance sensor BH1750 module, with low power consumption, strong commonality microcomputer STC89C52 as the microcontroller, it is a wireless sensor network environment monitoring system designed to meet the demand Of practical application. Practice has proved that, the system can monitor the indoor environment in real time, and it can be used in different occasions through the expansion of the terminal nodes, Compared to the Traditional conventional wired sensor monitoring system and the existing wireless sensor network monitoring system, it has the advantage of low cost, easy to decorate, strong expansibility, low power consumption, so it has high practical value.
