Want to bring a little more technology to your gardening? This sensor is perfect for you! This sensor is designed to be inserted into soil to measure the moisture content in the ground using an arduino or other microcontroller that has analog-to-digital conversion capabilities. The sensor can be used in analog mode, or in digital mode, outputting a digital high signal using the built in LM393 comparator, with triggering level adjustable with the built in potentiometer as well.

Operating voltage: 3.3-5V
