Tutorial: How to Use Water Flow Sensor YF-S201C

The YF-S201C water flow sensor is a useful device for monitoring the amount of water passing through a pipe. It is ideal for DIY projects such as water counters or hydraulic alarm systems.

What you need

• Arduino Uno
• Jumper Connections
• USB Cable
• Arduino IDE Software

Steps

1. Connect the sensor pins to the microcontroller: GND to ground, VCC to power supply (3.5-24VDC), OUT to the Arduino’s digital interface.
2. Open Arduino IDE and create a new sketch.
3. Insert the provided code to read data from the sensor.
4. Upload the sketch to the microcontroller.
5. Optimize sensor settings by checking the power supply voltage and measurement range (1-30L/Min).
6. Monitor water flow using Serial Monitor to view real-time data.
7. If necessary, add an LCD or OLED display for a more intuitive data visualization.
8. Test the sensor with various flow conditions to ensure its accuracy.

Example code

void setup() {
  Serial.begin(9600);
}

void loop() {
  int val = digitalRead(pinOUT); // Verifica sul datasheet il pin corretto
  if(val == HIGH) {
    Serial.println("Acqua in movimento");
  } else {
    Serial.println("Acqua fermo");
  }
}

Mini project

Create a water flow monitoring system that sends email notifications when the flow exceeds a certain threshold.

Common mistakes

• Connect the sensor to the wrong electrical voltage.
• Do not verify the correct pin OUT configuration.
• Omit testing the sensor with different flow conditions.
• Enter invalid data in the code.

Recommended accessories

Frequently asked questions

What is the minimum operating voltage for the YF-S201C sensor?
The minimum operating voltage is 3.5VDC, check the datasheet.

Can the sensor measure flows below 1L/min?
The sensor has a measurement range of 1-30L/Min, so it cannot detect values below 1L/min.

How can I integrate the sensor with a Wi-Fi network?
Use an ESP8266 module to send the water flow data to the cloud server.
