YF-S201 Water Flow Sensor Module – YFS201 Flowmeter for Arduino
YF-S201 Water Flow Sensor Module – YFS201 Flowmeter for Arduino
The YF-S201 (YFS201) Water Flow Sensor is a precise and easy-to-use device designed to measure water flow in DIY electronics and Arduino projects. It uses a Hall effect sensor to generate pulses that correspond to the rate of water flow, making it ideal for automated dispensing systems, vending machines, smart irrigation, and other IoT applications.
Simply connect the sensor to your microcontroller (e.g., Arduino, ESP32, Raspberry Pi) to monitor real-time water flow and volume accurately.
⚙️ Key Features:
- ✅ Flow Rate Measurement – Accurately measures water flow from 1–30L/min
- 💡 Hall Effect Sensor Technology – Converts flow into digital pulse output
- 💧 3/4” Standard Pipe Thread (G1/2”) – Easy to integrate into water lines
- 🔌 3-Wire Interface – Power (Red), Ground (Black), Signal (Yellow)
- 🔋 Low Power Consumption – Ideal for battery-powered or low-voltage systems
📦 Specifications:
- Model: YF-S201 / YFS201
- Flow Range: 1–30 Liters per Minute
- Working Voltage: 5V to 18V DC
- Working Current: ≤15mA (DC 5V)
- Output: Pulse signal (frequency proportional to flow)
- Accuracy: ±10%
- Maximum Pressure: ≤1.75 MPa
- Thread Size: G1/2" (3/4" external)
- Sensor Material: Plastic (nylon), with sealed internal components
💡 Applications:
- Arduino water flow metering projects
- Automatic water dispensers
- Smart irrigation systems
- Liquid dispensing or mixing systems
- Water vending or carwash machines
- Home automation and IoT water monitoring
