Description

A soil moisture sensor (or meter) measures the water content in soil. With it, you can easily tell when the soil needs more water or when it’s over-watered.

The Soil Moisture Sensor uses capacitance to measure the water content of soil (by measuring the dielectric permittivity of the soil, which is a function of the water content). Simply insert this rugged sensor into the soil to be tested, and the volumetric water content of the soil is reported in percent.

Feature:

1). Adjustable sensitivity by adjusting the digital potentiometer (shown in blue)
2). Operating voltage: 3.3V ~ 5V
3). Dual output mode, analog output more accurate.
4). A fixed bolt hole for easy installation
5). Panel PCB Dimension: 30mm  * 16mm
6). Soil Probe Dimension: 60mm * 30mm
7). With power indicator (red) and digital switching output indicator (green)
8). Having LM393 comparator chip, stable
