It features a G3/8 thread interface, making it compatible with pipes of this type. Features Type: Flow sensor / Water heater Technology: Hall Interface: G3/8 Thread Operating pressure: Check the datasheet Maximum flow rate: Check the datasheet Operating voltage: Check the datasheet What is it for? The YF-402C is ideal for home and industrial automation projects requiring fluid flow monitoring. Examples of use include creating water flow monitoring systems for tanks or managing liquid flow in industrial plants. Compatibility with Arduino and other microcontrollers makes it a versatile solution for IoT project creation. Tutorial: How to Use the YF-402C Flow Sensor The YF-402C measures fluid flow, ideal for home and industrial automation projects. What you need YF-402C Flow Sensor Arduino Power cable Pull-up resistor (10kΩ) Steps 1. Connect the sensor to the Arduino using a power cable. 2. Connect the pull-up resistor between the VCC pin of the sensor and GND of the Arduino. 3. Connect the GND pin of the sensor to the GND of the Arduino. 4. Connect the OUT pin of the sensor to the A0 pin of the Arduino. 5. Upload the following code to your Arduino. 6. Check the flow rate through the Serial Monitor console. 7. Verify correct power supply for the sensor on the datasheet. 8. Try varying the flow speed and observe changes in readings. Example Code “` void loop() { int flow = analogRead(A0); Serial.println(flow); delay(1000);} Mini-project Create a water flow monitoring system for a tank. Common errors Incorrect power supply: ensure correct voltage is supplied to the sensor. Wrong connections: carefully check electrical connections. Too high read frequency: reduce read frequency to avoid overload. Unconfigured Serial Monitor: ensure correct baud rate setting.
