🔌 3-Wire Interface:
  🔴 Red = VCC ⚫ Black = GND 🟡 Yellow = Pulse Output

📦 Package Includes
✅ 1x YF-S201 Water Flow Sensor
📄 Wire Leads: VCC, GND, Signal
🧰 Compatible with: Arduino, Raspberry Pi, ESP32, STM32, etc.

🧠 Perfect For
🚿 Smart water dispensers & purifiers
🌱 Automated garden/field irrigation
🛠️ Industrial liquid flow monitoring
📦 Water tracking for tanks & pump systems
🎓 DIY, IoT & STEM-based projects

🛠️ How It Works
1️⃣ Water flows through the sensor and spins a turbine
2️⃣ The turbine generates pulse signals as it spins
3️⃣ Each pulse is proportional to water flow (L/min)
📊 Microcontrollers count pulses to determine real-time flow rate

💡 Pro Tip: Connect with an OLED display or relay module to build your own smart water management or cutoff system! 💧📈
