摘要
为实现温湿度测量和无线数据传输,该设计使用AVR系列低功耗单片机ATmega16L作为控制芯片,低功耗芯片nRF905作为无线收发模块,并设计了基于数字温湿度传感器SHT11的温湿度无线测量系统,最后给出该系统的相关硬件组成电路和数据传输流程图。经测试,系统运行稳定可靠,通信距离很远,且温湿度测量精确,具有很广泛的应用前景。
In order to achieve temperature and humidity measurement and accomplish wireless data transmission, the system uses low- power single chip AVR series ATmegal6L as the control chip, and low - power chip nRF905 as a wireless transceiver module. It designs the digital temperature and humidity sensors based on the temperature and humidity SHTll wireless measurement system. At the same time, the correlative circuit of the system hardware and data transmission flow chart are given. The design involves a stable and reliable function, a long communication distance, and the precise measurement of temperature and humidity after tested,which has a very broad application prospects.
