“Have you ever wanted your plants to tell you when they need watered? Or know how saturated the soil in your garden is? With the SparkFun Soil Moisture Sensor, you can do just that! This tutorial will show you how to get started using the Soil Moisture Sensor as well as how to build your own soil moisture sensing project. If you prefer not to solder, you can purchase the sensor with a 3-pin screw terminal pre-soldered onto the board.”
