设计了一种基于Atmegal16单片机和NRF24L01无线芯片,DHT11数字温湿度传感器的多点无线温湿度采集系统。系统采用无线中继器进行组网,增加了温湿度测量点的数目。该系统能实现远距离、高效率、低成本的数据采集,并利用串行通信将采集到的数据传送到上位机进行分析处理。
A multi-point wireless temperature and humidity acquisition system based on Atmegal16 MCU and NRF24L01 wireless chip and DHT11 digital temperature and humidity sensor was designed. The system uses wireless repeaters for networking, increasing the number of temperature and humidity measurement points. The system can achieve long-distance, high-efficiency, low-cost data acquisition, and the use of serial communication will be collected data sent to the host computer for analysis and processing.
