Soil Moisture Sensor

Sensor for measuring soil moisture content

Features:

• Convenient for sensing soil moisture levels to prevent overwatering or underwatering.
• 2 probes act as variable resistors, allowing current to pass through soil to measure resistance and moisture.
• Fixed bolt hole for easy installation.
• Power indicator (red) and digital switching output indicator (green).
• Integrated LM393 comparator chip for stability.
• Dual output mode.
