Gorillacell Module 038: Capacitive Soil Moisture Sensor
Table of Contents
The Capacitive Soil Moisture Sensor measures soil moisture by detecting changes in capacitance caused by variations in the dielectric constant of the soil. As the moisture level increases, the dielectric value changes, allowing the sensor to determine how wet or dry the soil is.
Unlike resistive soil moisture sensors, the capacitive type is corrosion-resistant, providing better durability and long-term stability.
The Gorillacell ESP32 Development Kit includes one Capacitive Soil Moisture Sensor module for experimenting with soil monitoring and smart agriculture projects.

PINOUT
It has 3 pins which are
- GND - for the ground pin,
- VCC - for the supply voltage, and
- AOUT - for determining the analog value of the Capacitive Soil Moisture Sensor module.
An Analog to Digital Converter (ADC) peripheral will be used in order to determine the soil moisture percentage.
