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 . 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 . Soil moisture sensors measure the volumetric water content in soil. Since the direct gravimetric measurement of free soil moisture requires removing, drying, and weighting of a sample, soil moisture sensors measure the volumetric water content indirectly by using some other property of the soil, such as electrical resistance, . Delta-T Devices specialises in soil moisture sensors. Our comprehensive range includes sensors suited to a wide range of applications and budgets.
The accuracy, stability and reliability of our soil moisture sensors has made them the preferred choice of thousands of researchers world-wide. Continue reading “Soil moisture sensor”
