Product Details
YF-S201 Water Flow Sensor / Flowmeter (1/2" Hall Effect)
The YF-S201 Water Flow Sensor is a cost-effective and reliable solution for measuring the flow rate and total volume of liquids passing through a pipeline. This in-line sensor is comprised of a durable plastic valve body, a magnetic rotor assembly, and an integrated Hall Effect sensor that is sealed away from the fluid path.
When water flows through the sensor, the magnetic rotor spins, and the Hall sensor detects each revolution, generating a corresponding electrical pulse signal. By counting these pulses with a microcontroller, such as Arduino or Raspberry Pi (connected to a digital interrupt pin), the flow rate (in L/min) and the total volume (in Liters) can be precisely calculated using the sensor's linear K-factor formula.
🔧 Key Features
- Measurement Principle: Utilizes a magnetic Hall Effect sensor for non-contact flow detection.
- Flow Range: Accurately monitors flow from 1 L/min up to 30 L/min.
- Interface: Provides a digital 5V TTL Pulse Output for easy counting.
- Pipe Compatibility: Designed for installation on standard 1/2" nominal pipe connections.
- Durability: High-grade plastic construction and sealing, rated for up to 2.0 MPa (290 PSI) pressure.
- K-Factor: Simple conversion using the formula: Frequency (Hz) = 7.5 * Flow Rate (L/min).
💡 Applications
- Building Smart Irrigation and watering systems.
- Designing custom Fluid Dispensing machines (e.g., automated drink makers).
- Implementing Water Usage Monitoring in homes or offices.
- Flow rate measurement in Water Cooling systems.
