WCMCU-103 Rotary Angle Sensor

WCMCU-103 Rotary Angle Sensor

The WCMCU-103 Rotary Angle Sensor is a compact magnetic position sensor module designed for precise angle measurement and position detection. This sensor, which operates based on the Hall effect principle, provides long-lasting and reliable measurements without mechanical wear thanks to its contactless measurement capability.

Example Codes

Arduino Code for Angle Measurement with I²C

#include 

#define AS5600_ADDRESS 0x36
#define RAW_ANGLE_REG 0x0C

void setup() { 
Wire.begin(); 
Serial.begin(9600); 
Serial.println("AS5600 Angle Sensor Test");
}

void loop() { 
// Read angle value 
Wire.beginTransmission(AS5600_ADDRESS); 
Wire.write(RAW_ANGLE_REG); 
Wire.endTransmission(); 

Wire.requestFrom(AS5600_ADDRESS, 2); 
if (Wire.available() >= 2) { 
uint16_t rawAngle = (Wire.read() << 8) | Wire.read(); 
// Convert to 12-bit resolution (0-4095) 
rawAngle &= 0x0FFF;

// Convert angle to degrees (0-360)
float angleDegrees = rawAngle * 0.087890625; // 360 / 4096

// Print results
Serial.print("Raw Value: ");
Serial.print(rawAngle);
Serial.print("Angle (degrees): ");
Serial.println(angleDegrees);
}

delay(100);
}

Arduino Code for Analog Reading

const int analogPin = A0; // Pin to which you connect the analog output

void setup() {
Serial.begin(9600);
Serial.println("AS5600 Analog Output Test");
}

void loop() {
// Read analog value
int rawValue = analogRead(analogPin);

// Convert 0-1023 to 0-360 degrees
float angleDegrees = map(rawValue, 0, 1023, 0, 360);

// Print results
Serial.print("Raw Value: ");
Serial.print(rawValue);
Serial.print("Angle (degrees): ");
Serial.println(angleDegrees);

delay(100);
