描述
Grove – Water Sensor 水位感測器
水傳感器模組是 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。傳感器走線有一個1MΩ的弱上拉電阻。電阻將拉高傳感器跡線值，直到一滴水將傳感器跡線短接到接地跡線。您是否相信這個電路將與您的Arduino的數字I / O引腳一起工作，或者您可以使用它與模擬引腳一起檢測接地和傳感器走線之間的水分接觸量。
Grove – Water Sensor 水位感測器使用暴露的PCB走線檢測到水的存在。傳感器由交錯的地面和傳感器信號組成。傳感器走線使用1MΩ電阻微弱地上拉。電阻將拉高傳感器跡線值，直到一滴水將傳感器跡線短路到地面跡線。該電路將與Arduino的數字I / O引腳一起工作，或者您可以將其與模擬引腳配合使用，以檢測接地和傳感器走線之間的水分接觸量。
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.
