SparkFun Soil Moisture Sensor 土壤濕度感測器
SparkFun土壤濕度傳感器是測量土壤和類似材料濕度的簡單Breakout。土壤濕度傳感器非常簡單易用。兩個大的裸露焊盤作為傳感器的探針，一起作為一個可變電阻。在土壤中的水越多意味著墊之間的導電性越好，並且將導致更低的電阻和更高的SIG輸出。

為了使SparkFun土壤濕度傳感器正常工作，您只需將VCC和GND引腳連接到基於Arduino的器件（或兼容的開發板），您將收到一個SIG，這取決於土壤中的水量。土壤濕度傳感器的一個普遍已知的問題是當暴露在潮濕的環境中時，它們的壽命很短。為了解決這個問題，我們使用鍍金（ENIG或無電鍍鎳浸金）塗覆了PCB。我們建議使用一個簡單的3針螺絲針端子或3針跳線組件（均可在下面的推薦產品部分找到）焊接到傳感器上，以便於連線。

注意：請查看下面的連接指南，了解組裝和防水說明以及一個簡單的示例項目，您可以將它們放在一起！

The SparkFun Soil Moisture Sensor is a simple breakout for measuring the moisture in soil and similar materials. The soil moisture sensor is pretty straight forward to use. The two large exposed pads function as probes for the sensor, together acting as a variable resistor. The more water that is in the soil means the better the conductivity between the pads will be and will result in a lower resistance, and a higher SIG out. To get the SparkFun Soil Moisture Sensor functioning all you will need is to connect the VCC and GND pins to your Arduino-based device (or compatible development board) and you will receive a SIG out which will depend on the amount of water in the soil. One commonly known issue with soil moisture senors is their short lifespan when exposed to a moist environment. To combat this, we’ve had the PCB coated in Gold Finishing (ENIG or Electroless Nickel Immersion Gold). We recommend either a simple 3-pin screw pin terminal or a 3-pin jumper wire assembly (both can be found in the Recommended Products section below) to be soldered onto the sensor for easy wiring. Note: Check the Hookup Guide below for assembly and weatherproofing instructions as well as a simple example project that you can put to together yourself!
