商品說明

Grove – Water Sensor 水感測器

水傳感器模塊是Grove系統的一部分。它通過測量電導率指示傳感器是否乾燥,潮濕或完全浸入水中。傳感器走線使用1MΩ上拉電阻。電阻將拉高傳感器的數值,直到水將傳感器的信號線短接到地。此電路將使用Arduino的數字I / O引腳,您也可以使用模擬引腳來檢測地和傳感器信號線之間水的接觸量。

Grove – Water Sensor

Grove – Water Sensor detects the presence of water using exposed PCB traces. The sensor is made up of interlaced traces of Ground and Sensor signals. The sensor traces are weakly pulled up using 1 MΩ resistor. The resistor will pull the sensor trace value high until a drop of water shorts the sensor trace to the ground trace. This circuit will work with digital I/O pins of Arduino or you can use it with the analog pins to detect the amount of water induced contact between the grounded and sensor traces.
