DFRobot原廠 Gravity: Analog Water Pressure Sensor 模擬量水壓傳感器 (SEN257)
【清單】
- 模擬量水壓傳感器x1
- G1/2轉G1/4轉接頭(已安裝)x1
水壓傳感器是一種適用於管道壓力檢測的設備,可以檢測容器內各類非腐蝕性液體和氣體的壓力。不僅可以用來測量液位高度,也可以用來檢測管道內是否存在有漏水,堵塞或者凍結等問題。再進一步通過對傳感器信號進行分析和換算後,可以了解到一個容器內是否存在液體,包括液位的高度,也能一併測量出來。可以廣泛應用於農業灌溉、花園苗圃、魚塘養殖等用水場合。
本款水壓傳感器採用DFRobot Gravity標準3-Pin接口,標準5V供電,0.5~4.5V線性電壓輸出,可兼容各種Arduino控制器。配合DFRobot Gravity IO Expansion Shield,可直插Arduino。無需額外接線。
當它配合DFRobot電磁閥、微型水流發電機以及其它傳感器使用時,還可以通過編程和硬件組合的方式設計出許多智能的系統。可以說,水壓傳感器就像是貼著水管的聽診器,它會告訴你許多水的信息,包括水的強弱,水的有無。
傳感器內部採用矽單晶材料,借助其在受到外力作用下電阻率會發生變化的現象(壓阻效應原理),可以用來檢傳感器是否受到壓力,其變化的阻值與受到的壓力成正比對應關係。

注意事項:
1. 測量之前應確保連接部分的密閉性
2.由於傳感器工作條件為-20~85 ℃,所以應避免在超出範圍的環境下使用

INTRODUCTION
This is a water pressure sensor adopts DFRobot Gravity 3-pin interface. It supports standard 5V voltage input and 0.5~4.5V linear voltage output. It is compatible with multiple
Arduino controllers. Coordinate with a
DFRobot Gravity IO Expansion Shield, the water pressure sensor can be plugged into an Arduino board, wiring-free. Put it with
Solenoid Valve,
Water Turbine Generator and other sensors, you can build a smart water control system.
