The HW-517 features a simple pinout for easy integration. Below is the pin configuration:

The HW-517 is straightforward to use in a variety of circuits. Follow the steps below to integrate it into your project:

1. Power Supply: Connect the VCC pin to a 3.3V or 5V power source and the GND pin to the ground of your circuit.
2. Signal Input: Connect the signal source (e.g., a sensor or microcontroller) to the Signal Input pin.
3. Signal Output: Connect the Signal Output pin to the next stage of your circuit, such as an ADC (Analog-to-Digital Converter) or another processing module.

• Ensure the input signal voltage does not exceed the operating range (0V to 5V) to avoid damage.
• Use decoupling capacitors (e.g., 0.1µF) near the VCC pin to reduce noise and improve stability.
• If using the HW-517 with an Arduino UNO, ensure the power supply matches the Arduino's logic level (5V).

Below is an example of how to connect and use the HW-517 with an Arduino UNO to read and process a signal:

• Connect VCC to the Arduino's 5V pin.
• Connect GND to the Arduino's GND pin.
• Connect the Signal Input to an analog sensor output.
• Connect the Signal Output to an analog input pin on the Arduino (e.g., A0).

// Example code to read and display the HW-517 output using Arduino UNO

const int signalOutputPin = A0; // HW-517 Signal Output connected to A0

void setup() {
  Serial.begin(9600); // Initialize serial communication at 9600 baud
  pinMode(signalOutputPin, INPUT); // Set A0 as input
}

void loop() {
  int signalValue = analogRead(signalOutputPin); // Read the signal value
  float voltage = (signalValue / 1023.0) * 5.0; // Convert to voltage (0-5V range)

  // Print the signal value and voltage to the Serial Monitor
  Serial.print("Signal Value: ");
  Serial.print(signalValue);
  Serial.print(" | Voltage: ");
  Serial.println(voltage);

  delay(500); // Wait for 500ms before the next reading
}

• Use proper grounding techniques to minimize noise in the circuit.
• Avoid exposing the HW-517 to extreme temperatures or humidity to ensure long-term reliability.
• Test the component in a breadboard setup before finalizing the design.

1. No Output Signal:

   • Cause: Incorrect power supply or loose connections.
   • Solution: Verify that the VCC and GND pins are properly connected and the power supply is within the specified range.

2. Output Signal is Noisy:

   • Cause: Insufficient decoupling or external interference.
   • Solution: Add a 0.1µF capacitor near the VCC pin and ensure proper grounding.

3. Signal Output is Clipped:

   • Cause: Input signal exceeds the specified range (0V to 5V).
   • Solution: Ensure the input signal is within the acceptable range or use a voltage divider to scale it down.
