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.

在SparkFun土壤水分傳感器是測量土壤和類似材料中的水分一個簡單的突破。土壤濕度傳感器是非常簡單的使用。兩個大暴露焊盤用作探針的傳感器，一起充當可變電阻器。水越多即在土壤裝置的襯墊之間的更好的導電性將是，將導致較低的電阻和較高的SIG出來。
要獲得SparkFun土壤水分傳感器功能的所有你需要的是將VCC和GND引腳到基於Arduino的設備（或兼容的開發板），您將收到一個SIG出這將取決於水的量在土壤。當暴露於潮濕的環境與土壤濕度senors一個公知問題是它們的壽命短。為了解決這個問題，我們已經塗在黃金整理（ENIG或化學鍍鎳浸金）的PCB。我們建議無論是簡單的3針螺釘針端子或3針跳線組件（既可以在下面的推薦產品部分中找到）被焊接到傳感器接線方便。
