YF-DN40 1.5 inch is a plastic body water flow sensor that contains a water rotor and a hall-effect sensor and is used for flow measurement for industrial applications. When the water flows through the rotor, the rotor rolls, and its speed changes with a different rate of flow. The hall-effect sensor outputs the corresponding pulse signal. The output of the flow sensor is proportional to the water flow. The more the water flowing more are the pulses.


Features:

  1. Accuracy in 1 ~ 120L / MIN  ± 2% inline
  2. Flow pulse characteristics F = (0.45 * Q) Q = L / Min meet
  3. Low-temperature test at -20'C temperature placed after 72h, at room temperature for 1h, the first measurement accuracy within ± 5% value inline
  4. High-temperature test temperature at 85'C placed after 72h, at room temperature for 1h, the first measurement accuracy within ± 5% value
  5. 11/2" DN40 flow rate 5~150L/min  Plastic Hall Turbine flow sensor meter  switch valve control liquid flow sensor

Package Includes:

1 x YFDN40 Water Flow Sensor Flowmeter G11/2 5- 150L/Min

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.
