Description Share this productYF-S201 1/2 inch Water Flow Sensor sits in line with the water line and contains a pinwheel sensor to measure how much water has moved through it. There is an integrated magnetic Hall-Effect sensor that outputs an electrical pulse with every revolution. YF-S201 1/2 inch water flow sensor has only three wires and it can be easily interfaced between any microcontroller and Arduino board. It requires only 5V Vcc and gives pulse output, the sensor needs to be tightly fitted between water pipeline. Specifications: Model: YF-S201 Sensor Type: Hall effect Working Voltage: 5 to 18V DC (min tested working voltage 4.5V) Max current draw: 15mA @ 5V Output Type: 5V TTL Working Flow Rate: 1 to 30 Liters/Minute Working Temperature range: -25 to 80℃ Working Humidity Range: 35%-80% RH Accuracy: ±10% Maximum water pressure: 2.0 MPa Output duty cycle: 50% -10% Output rise time: 0.04us Output fall time: 0.18us Flow rate pulse characteristics: Frequency (Hz) = 7.5 * Flow rate (L/min) Pulses per Liter: 450 Durability: minimum 300,000 cycles *Product images are shown for illustrative purposes only and may differ from actual product.
