[elecena] Gravity: Digital Water Flow Sensor For Arduino - 1/8" - zmiany ceny The Water Flow sensor measures the rate of a liquid flowing through it. The YF-S401 water flow sensor consists of a plastic valve body, flow rotor and hall effect sensor. It is usually used at the inlet end to detect the amount of flow. When liquid flows through the sensor, a magnetic rotor will rotate and the rate of rotation will vary with the rate of flow. The hall effect sensor will then output a pulse width signal. Connect it to a microcontroller and you can monitor multiple devices such as your coffee maker, sprinkler or anything else, and control the water flow rate to suit your needs! Note: * A 6 mm hose is recommended * Avoid unit contact with corrosive chemicals * The unit must be installed vertically, tilted no more than 5 degrees * Liquid temperature should be less than 120 C to avoid damage to unit Connection Example - DFRduino UNO R3 Specifications * Inner Diameter: 4 mm * Outside diameter: 7 mm * Proof Water Pressure: <0.8 MPa * Water Flow Range: 0.3-6 L/min * Voltage Range: 5~12 V * Operating Current: 15 mA (DC 5V) * Insulation Resistance: >100 MΩ * Accuracy: ±5% (0.3-3L/min) * The Output Pulse High Level: >4.5 VDC (DC input voltage 5 V) * The Output Pulse Low Level: <0.5 VDC (DC input voltage 5 V) * Output Pulse Duty Ratio: 50% ± 10% * Water-flow Formula: 1L = 5880 square waves * Working Humidity Range: 35% ~ 90% RH (no frost) * Dimension: 58 x 35 x 26 mm * Weight: 30g Resources * Product Wiki Package Contents * 1x Water Flow Sensor - 1/8" Gravity: Digital Water Flow Sensor For Arduino - 1/8" - 6.88 GBP https://elecena.pl/product/22715021/gravity-digital-water-flow-sensor-for-arduino-1-8 2023-03-06 Gravity: Digital Water Flow Sensor For Arduino - 1/8" - 7.08 GBP https://elecena.pl/product/22715021/gravity-digital-water-flow-sensor-for-arduino-1-8 2023-12-27 Gravity: Digital Water Flow Sensor For Arduino - 1/8" - 8.50 GBP https://elecena.pl/product/22715021/gravity-digital-water-flow-sensor-for-arduino-1-8 2024-09-19 Gravity: Digital Water Flow Sensor For Arduino - 1/8" - 6.80 GBP https://elecena.pl/product/22715021/gravity-digital-water-flow-sensor-for-arduino-1-8 2024-11-29 Gravity: Digital Water Flow Sensor For Arduino - 1/8" - 8.50 GBP https://elecena.pl/product/22715021/gravity-digital-water-flow-sensor-for-arduino-1-8 2024-11-30 Gravity: Digital Water Flow Sensor For Arduino - 1/8" - 8.80 GBP https://elecena.pl/product/22715021/gravity-digital-water-flow-sensor-for-arduino-1-8 2025-02-13 Gravity: Digital Water Flow Sensor For Arduino - 1/8" - 8.50 GBP https://elecena.pl/product/22715021/gravity-digital-water-flow-sensor-for-arduino-1-8 2025-04-11 Gravity: Digital Water Flow Sensor For Arduino - 1/8" - 8.60 GBP https://elecena.pl/product/22715021/gravity-digital-water-flow-sensor-for-arduino-1-8 2025-08-05 Gravity: Digital Water Flow Sensor For Arduino - 1/8" - 6.88 GBP https://elecena.pl/product/22715021/gravity-digital-water-flow-sensor-for-arduino-1-8 2025-11-28 Gravity: Digital Water Flow Sensor For Arduino - 1/8" - 8.60 GBP https://elecena.pl/product/22715021/gravity-digital-water-flow-sensor-for-arduino-1-8 2025-11-29
