Description: Soil Moisture Sensor Module 1. Function: This module measures the moisture level in soil, delivering real-time data for irrigation systems, hydroponics, and agricultural applications. 2. Design: The sensor consists of two probes - one to measure volumetric water content in the soil and another for reference. It's typically made of ceramic or stainless steel materials with a protective epoxy coating. 3. Measurement Principle: It uses capacitance technology to determine moisture levels by measuring changes in electrical capacitance between the probes as water content varies. 4. Operating Conditions: Suitable for temperatures ranging from 0°C to +60°C and can handle a wide range of soil types, including sandy, clay, or loamy. 5. Installation: Easy setup using simple wiring connections: power supply, ground, and sensor output. Compatible with various microcontrollers and IoT platforms for data logging and remote monitoring. 6. Accuracy and Resolution: Offers high accuracy (±3%) and a goo
