May 11, 2020 · There are a variety of flow sensors of different principles, but for makers using Arduino or Raspberry Pi, the most common flow sensor is based on a Hall device. For example, the most classic water flow sensor YF-S402 and YF-S201 rely on Hall sensors. So, how does the Hall water flow sensor work? How does the water flow sensor work?

Water Flow Sensor YF-S402 This water flow sensor is basically a small turbine whose output signal is a series of digital pulses. The frequency of the pulses is proportional to the flow rate of the liquid passing through the sensor. That digital signal, whose frequency is in …

YF-S402 Water Circulation Sensor. This water move sensor is mainly a small turbine whose output sign is a collection of digital pulses. The frequency of the pulses is proportional to the move charge of the liquid passing by the sensor.

Specifications: Flow sensor, YF-S402 model, 0.3-6L monitoring range, 3% accuracy, 0.35MPa water pressure resistance, DC5~24V working voltage range, >100MΩ insulation resistance, (0.15-3L/Min) ±2% accuracy

In this tutorial you will learn how to use one water flow sensor with an Arduino board. The water flow sensor consists of a plastic valve body, a water rotor and a hall-effect sensor. When the water flows through the rotor, rotor rolls and the speed of it changes with a different rate of flow.

YF-S402 Hall Effect Water Flow Meter / Sensor. This sensor sits in line with your water line and contains a pinwheel sensor to measure how much liquid has moved through it. There's an integrated magnetic hall effect sensor that outputs an electrical pulse with every revolution.

Water flow sensor consists of a plastic body, the flow of the rotor assembly and a Hall sensor. Signal feedback to the controller, the controller is determined by the size of the water traffic regulation. Non-violent shocks and chemical erosion. Prohibited throw or collision. Vertical mounting inclination of not more than 5 degrees.

Mar 26, 2025 · That digital signal, whose frequency is in the range between 0Hz and 100Hz, can be read directly through one of the digital input/output pins of a microcontroller. This water flow sensor is basically a small turbine whose output signal is a series of digital pulses.

The YF-S402 Hall Effect Water Flow Meter Sensor consists of a plastic valve body, a water rotor, and a hall-effect sensor. When water flows through the rotor, the rotor rolls. Its speed changes with different rates of flow.
