The SparkFun Soil Moisture Sensor is a simple breakout for measuring the moisture in soil and similar materials. The soil moisture sensor is pretty straightforward 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, resulting in a lower resistance and a higher SIG out. This version of the Soil Moisture Sensor includes a 3-pin screw pin terminal pre-soldered to the board for easy wiring and setup.
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). 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).

SparkFun土壤水分傳感器是測量土壤和類似材料中的水分的簡單突破。土壤水分傳感器非常簡單易用。兩個大的裸露焊盤用作傳感器的探頭，共同作為可變電阻器。在土壤中越多的水意味著焊盤之間的電導率越好，導致較低的電阻和更高的SIG輸出。該版本的土壤水分傳感器包括一個預先焊接到板上的3針螺絲銷端子，便於接線和設置。
為了使SparkFun土壤水分傳感器發揮作用，您需要將VCC和GND引腳連接到基於Arduino的設備（或兼容的開發板）上。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常見問題是暴露於潮濕環境時的壽命短。為了解決這個問題，我們已經將PCB塗上黃金整理（ENIG或無電鍍鎳浸金）。
