Why Buy from Elecvora?

Elecvora sources this product directly, cutting out multiple middlemen. Every order includes free shipping, a 15-day return policy, and secure payment via Razorpay.

The YFS403 3.5-24V Water Flow Sensor mainly consists of a plastic valve, water flow rotor assembly, and a Holzer sensor. The rotation of the magnetic rotor and the rotating speed change with the change of the flow rate, and the output of the Holzer sensor is corresponding to the pulse Signal, feedback to the controller, by the controller to determine the size of the water flow, control.

It is installed in the hot water inlet end for detecting water flow. When water through the flow rotor assembly, the magnetic rotor will rotate and Speed will change as the flow change. Hall current sensor output corresponding pulse signal and feedback to the controller, then the controller will control the flow. Can be used for water heaters, credit card machines, water vending machine, flow measurement device.

Wire Connections:
  • Red: Positive(+)
  • Yellow: Signal output.
  • Black: Negative(-)

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
