感應式數字水位傳感器在傳統的應用中，采集數據的傳輸都是采用有線傳輸。由于傳統有線網絡本身的局限性，許多特殊的環境下網絡覆蓋和網絡支持仍然是個難題。針對這個問題，提出了基于ZigBee無線通信技術的便攜式數字水位傳感器無線變送器的設計方案。該變送器體積小，成本低，可操作性強，現場安裝簡單。由于采用ZigBee技術，更加適合組建有大量的現場數據采集點的監控系統，且組網靈活，極大地擴展了感應式數字水位傳感器的應用范圍。

　　Abstract:

　　In traditional applications of inductive digital water-level sensor， data acquired was transmitted by wire transmission. Owing to the limitations of traditional cable-Network itself， the coverage and technical support of cable-network is still a problem in many special circumstances. To address this issue， the design of wireless transmitter of portable digital water-level sensor based on ZigBee wireless communication technology is proposed in this paper. There are many advantages of this transmitter， such as small size， lower cost， easy operation， simple on-site installation， and so on. As a result of adopting the ZigBee technology， it is more suitable to construct a monitoring system of a large amount of on-site data collection point and flexible to construct network， and greatly extends the applications area of the digital water-level sensor.
