⚙️ Comparator Chip: LM393 for stable digital output
📟 Output: Analog (AO) + Digital (DO)
⚡ Operating Voltage: 3.3V – 5V DC
🔧 Adjustable Sensitivity via onboard potentiometer
💡 Onboard power & signal indicator LEDs

🧰 Package Includes
✅ 1x Soil Moisture Sensor Probe
✅ 1x Comparator Driver Board (LM393)
📄 Pins: VCC, GND, AO, DO
🧰 Fully compatible with Arduino, ESP32, Raspberry Pi, etc.

🧠 Perfect For
🌿 Smart irrigation systems
🏡 Home gardening automation
🚜 Agricultural monitoring projects
📊 Soil condition data logging
🎓 STEM & school science kits

🛠️ How It Works
1️⃣ Sensor probes detect water content in the soil
2️⃣ AO gives analog value (for real-time moisture level)
3️⃣ DO goes HIGH or LOW depending on soil dryness (adjustable)
4️⃣ Use it to turn on a water pump, buzzer, or LED

🧠 Pro Tip: Combine it with a relay module and mini pump for a fully automated watering system! 💧
