為降低設計成本，利用CXA1191和SHT11實現(xiàn)了一個無線溫濕度監(jiān)測系統(tǒng)。在CXA1191原有的廣播接收功能的基礎上，巧妙結合編碼技術，成功實現(xiàn)了數(shù)據(jù)無線傳輸功能，并選擇SHT11實現(xiàn)高性能的溫濕度采集。系統(tǒng)的特色在于將成熟的廣播接收技術與數(shù)字技術相融合，具有較高的性價比，很好地滿足了無線溫濕度數(shù)據(jù)采集需求。

　　Abstract:

　　In order to reduce cost， this paper realized a wireless temperature and humidity monitoring system with CXA1191 and SHT11.Based on the original radio receiving function of CXA1191 and combined with coding technology， the design realized wireless data transmission successfully， and chose SHT11 gathering temperature and humidity. The distinguishing feature of the system is the integrating of radio receiving technology and digital technology， it has high performance and price ratio. It will well meets the wireless temperature and humidity data acquisition needs
