EC-5 Soil Moisture Sensor
Overview
The EC-5 by METER is a high-frequency capacitance sensor designed to measure the volumetric water content (VWC) of soil and other porous media. Its 70 MHz frequency minimizes salinity and textural effects, making it a reliable choice for research and commercial agriculture.
Why Choose This Part
The EC-5 features a compact 5cm length that minimizes soil disturbance while providing accurate readings across a wide range of soil types. Its low power requirement and analog output make it easily compatible with most data loggers and microcontrollers.
Applications
Getting Started
To use the EC-5, provide an excitation voltage between 2.5V and 3.6V and measure the analog output voltage. Calibrate the sensor using standard soil-specific equations to convert the millivolt output into volumetric water content (VWC).
