Soil Moisture Sensor Module for Arduino

Description

Soil Humidity & Moisture Detection Sensor Module
A simple yet effective water sensor designed to detect soil moisture levels. When soil moisture falls below the set threshold, the module outputs a high signal; when moisture is sufficient, it outputs a low signal. Ideal for building an automatic plant watering system, allowing your garden to thrive without constant manual monitoring.
Key Features:
Adjustable sensitivity via onboard blue digital potentiometer
Operating voltage: DC 3.3V–5V
Dual output mode — digital output and analog output for greater accuracy
Mounting holes included for easy installation
Compact PCB size: 30 × 16 mm (3 × 1.6 cm)
Power indicator (Red LED) and digital switch output indicator (Green LED)
Built-in LM393 comparator chip for stable and reliable performance
