GY-271 HMC5883L Compass Magnetometer Module Magnetic current and field have directly relation with each other. When current flows in a wire (electrons start travelling in one direction), a magnetic field is created. The main idea of compass sensors is based on this relationship. The direction of the earth’s magnetic field affects the flow of electrons in the sensor. By measuring these changes in current, the sensor will be able to detect direction. The GY-271 module uses the QMC5883L chip to detect magnetic fields and its directions. The communication protocol of this module is I2C and you can connect it to different processors such as Arduino boards using two SCL and SDA pins. Pinout: VCC : Module power supply – 3 to 5 volts GND: Ground SCL: I2C Clock pin SDA: I2C Data pin DRDY (Data Ready) : When the output value of the sensor is ready, an interrupt occurs in this pin. This pin is pulled up inside the module by default. When the output value of the module is ready, the pin is “0” for 250 microseconds Features: Gold plating PCB, applying machine welding technology, superb technique and reliably quality guarantee!
