Soil Moisture Sensor 土壤濕度 傳感器/感測器

SparkFun 土壤濕度 傳感器 感測器 是一種簡單的分析儀，用於測量土壤和類似材料中的水分。土壤濕度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。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。

要獲得SparkFun土壤濕度傳感器的功能，您需要的是將VCC和GND引腳連接到基於 Arduino設備（或兼容的開發板），您將收到一個SIG輸出，這將取決於土壤中的水量。土壤濕度傳感器的一個眾所周知的問題是當暴露於潮濕環境時它們的壽命短。為了解決這個問題，我們已經用金塗層（ENIG或Electroless Nickel Immersion Gold）塗覆了PCB。我們建議將簡單的3針螺旋針端子或3針跨接線組件焊接到傳感器上，以便於接線。

SparkFun Soil Moisture Sensor

 

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.
