Soil Moisture sensor
Description
- The Soil Moisture Sensor Module (YL-69 + FC-28) is a resistive soil humidity detection device used to measure water content in soil.
- It provides both analog (AO) and digital (DO) outputs with adjustable sensitivity using an onboard LM393 comparator.
- Ideal for smart irrigation systems, plant monitoring, Arduino, and IoT-based environmental projects.
