SEN0193 Capacitive Soil Moisture Sensor
Overview
The DFRobot SEN0193 is a capacitive soil moisture sensor module designed for embedded projects and educational use. It provides an analog output voltage proportional to the moisture level in the soil, making it suitable for basic environmental monitoring and plant care systems. Unlike resistive sensors, its capacitive design helps prevent corrosion over time.
Why Choose This Part
This sensor offers a simple analog interface, making it easy to connect to most microcontrollers. Its capacitive sensing principle improves longevity compared to resistive sensors by avoiding direct electrode contact with soil, which can lead to corrosion. The Gravity interface simplifies wiring for DFRobot ecosystem users.
