Seeed Grove – Capacitive Moisture Sensor 電容式土壤濕度感測器 (耐腐蝕) 解決電極生鏽 | Arduino 適用

商品說明

Capacitive Moisture Sensor 土壤濕度感測器是一種檢測土壤體積含水量的感測器。 Grove 電容式土壤濕度感測器（耐腐蝕）是一種基於電容變化的土壤濕度感測器。與電阻式感測器相比，電容式感測器不需要直接暴露金屬電極，可以顯著減少電極的腐蝕。需要注意的是，這種感測器只能定性測試土壤的濕度，不能定量測量。當土壤濕度升高時，輸出值減小；相反，當濕度降低時，輸出值會變高。

Capacitive Moisture Sensor 技術補充（英文）

以下為原廠英文技術說明，提供使用者參考。

A soil moisture sensor is one that detects the volumetric water content of the soil. The Grove – Capacitive Soil Moisture Sensor (Corrosion Resistant) is a soil moisture sensor based on capacitance changes. Compared with resistive sensors, capacitive sensors do not require direct exposure of the metal electrodes, which can significantly reduce the erosion of the electrodes. Hence, we call it Corrosion Resistant.

It is important to note that this sensor can only qualitatively test the humidity of the soil and cannot measure quantitatively. When the humidity of the soil rises, the value of the output decreases; conversely, when the humidity decreases, the output value becomes higher.

Feature

• Capacitive Style
• Corrosion Resistant
• Built-in Amplifier

Typical Applications

• Soil moisture detection
• Automatic watering of plants

What is Grove?

Grove makes it easier to connect, experiment, and simplify the prototyping process. No jumpers or soldering required. We have developed more than 300 Grove modules, covering a wide range of applications that can fulfill a variety of needs. Not only are these open hardware, but we also have open-source software.
