摘要
本文介绍了一种基于nRF905的温室环境无线测控系统,可对室内温湿度实时监测、报警以及温湿度参数线性补偿。系统选择智能数字温湿度传感器DHT21(AM2301)对温湿度数据进行采集,通过下位机MCU进行处理,实时显示温湿度参数值,并根据设定的温湿度限制参数进行相应的智能控制。通过nRF905无线发射模块实现数据通信。经测试,该系统运行稳定可靠,并具有良好的扩展性和发展前景。
A wireless control system of greenhouse based on nRFg05 is designed in this paper,to measure temperature and hu- midity in greenhouse,alarm the anomaly on environment parameters,and compensate the parameters linearly,In this system,we use DHT21（AM2301） for temperature and humidity measurement,and deal with the data through the MCU,the data is sent to micropro- cessor directly,we accomplish intellectual control according to the setting on the corresponding parameters.Data communication is accomplished by nRFg05.Through experiments show that the system is stable and reliable,and has good expansibility and devel- opment prospects.
