摘　　要：系统以单片机STC89C52RC作为控制处理核心,采用芯片nRF905为无线传输模块,HS1100/HS1101传感器采集湿度信号,设计了一种无线仓储湿度检测仪。经实验测试表明:系统湿度检测范围为10%RH^100%RH;精度达±1%RH,数据无线传输距离200米。设计的系统符合预期要求,可在仓储日常管理、气象、酒厂等不易布线,且需要实时监测湿度参数的场合推广应用。The system with STC89C52RC MCU as control core uses nRF905 chip as the wireless transmission module, signal acquisition and humidity sensor HS1100/HS1101, and this paper designs a wireless storage humidity detector. The experimental result shows that the range of the system for humidity detection ：10% RH - 100% RH;the accuracy of detection ± 1% RH;the transmission distance of data wireless： 200 meters. The design of the system meets the expected requirements, it can be applied to in some situations that are uneasy to wire in and need to be monitored for real-time moisture parameters, such as： daily management, meteorological phenomena and winery for storage.
