摘要
为了实时监控档案库房环境的温湿度参数，确保档案保存质量，系统以单片机STC89C52RC作为微处理器，采用芯片nRF24L01为无线传输模块，采集温湿度信号，设计了一种无线温湿度检测系统。系统硬件电路采用模块化结构，使得系统兼容性、扩展性、稳定性很好。经实验测试表明：系统温度测量精度达0．5℃，湿度测量精度达1％RH，在内无线传输距离达50米。设计的系统符合预期要求，可在博物馆、档案室、图书馆空间狭小不易布线的环境推广应用。
In order to temperature and humidity parameters real - time monitoring archives environment, ensure the quality of archives preservation, system with STC89C52RC MCU as the microprocessor, using nRF24L01 chip as the wireless transmission module, acquisition of temperature and humidity signal, the design of a wireless temperature and humidity detection system. The hardware circuit of the system adopts modular structure, make the system compatibility, expansibility, good stability. The experimental result shows ： the temperature measurement accuracy of the system reaches 0.5℃, humidity measurement precision of 1% RH, including wireless transmission distance of 50 meters. The design of the system meets the expected record room, narrow space is not easy wiring. requirements, application environment in the museum,library,
