How to Use xkc-y26-v contactless water level sensor: Examples, Pinouts, and Specs

The XKC-Y26-V is a contactless water level sensor designed to detect water levels without direct contact with the liquid. This sensor is ideal for non-invasive applications, making it suitable for measuring liquid levels in containers where direct contact with the liquid is undesirable or impractical. Common applications include water dispensers, coffee machines, and other household appliances, as well as industrial liquid level monitoring systems.

1. Power Supply: Connect the VCC pin to a 5V DC power supply and the GND pin to the ground of your circuit.
2. Output Signal: Connect the OUT pin to a digital input pin on your microcontroller (e.g., Arduino UNO).

+5V (Arduino) ----> VCC (XKC-Y26-V)
GND (Arduino) ----> GND (XKC-Y26-V)
Digital Pin (Arduino) ----> OUT (XKC-Y26-V)

// Define the pin connected to the sensor's OUT pin
const int sensorPin = 2;

// Variable to store the sensor state
int sensorState = 0;

void setup() {
  // Initialize the serial communication
  Serial.begin(9600);
  
  // Set the sensor pin as an input
  pinMode(sensorPin, INPUT);
}

void loop() {
  // Read the state of the sensor
  sensorState = digitalRead(sensorPin);
  
  // Check if water is detected
  if (sensorState == HIGH) {
    Serial.println("Water detected!");
  } else {
    Serial.println("No water detected.");
  }
  
  // Wait for a short period before reading again
  delay(500);
}

• Ensure the sensor is properly aligned with the container's surface for accurate detection.
• Avoid using the sensor with metallic containers, as it is designed for non-metallic materials.
• Keep the sensor clean and free from dust or debris to maintain optimal performance.
• Test the sensor in your specific application to ensure it meets your requirements.

1. Sensor Not Detecting Water:

   • Solution: Ensure the sensor is properly connected to the power supply and ground. Check the alignment with the container and ensure the container is non-metallic.

2. False Positives/Negatives:

   • Solution: Verify that the sensor is clean and free from obstructions. Adjust the sensor's position and ensure it is securely attached to the container.

3. Intermittent Readings:

   • Solution: Check for loose connections in the wiring. Ensure the power supply is stable and within the specified voltage range.

Q: Can the XKC-Y26-V sensor be used with any type of liquid? A: The sensor is designed for water and similar liquids. It may not work accurately with highly viscous or non-conductive liquids.

Q: What is the maximum thickness of the container wall for accurate detection? A: The sensor can detect water levels through non-metallic container walls up to 20mm thick.

Q: Is the sensor waterproof? A: Yes, the XKC-Y26-V has an IP67 waterproof rating, making it suitable for use in wet environments.

Q: Can I use multiple sensors in the same project? A: Yes, you can use multiple sensors by connecting each sensor's OUT pin to a separate digital input pin on your microcontroller.

By following this documentation, you should be able to effectively integrate the XKC-Y26-V contactless water level sensor into your projects, ensuring accurate and reliable water level detection.
