Overview

The soil moisture sensor measures the amount of water present in soil. The probes sense the level of conductivity of the soil to determine the moisture content. It converts changes in conductivity to analog voltage signals, allowing

the controller to read the values for various applications. This type of sensor is often used in smart agriculture, automatic irrigation, and environmental monitoring.

Features

• 3.3 – 5V operating voltage

• Provides analog output (AOUT) which changes with soil moisture

• Simple design, easy to install, and has various applications

• Can be used as a practical sensor in teaching or special projects

Applications

• Soil moisture monitoring in smart agriculture

• Provide start and stop conditions for automatic irrigation

• Greenhouse soil moisture management

• Soil dryness alarm and reminder

Electrical Characteristics

Glossary:

*Typical refers to the average/common value for each parameter. This presents the most common reference value under standard conditions. It can be used as a basis for the general performance of the component under normal working conditions.
