CIRCUIT CONNECTION
- The GND Pin of GY-511 is connected with GND pin in Arduino Uno board and VCC Pin of GY-511 is attached to 3.3V to build a simple circuit which is capable of measuring the waving motion.
- The SDA Pin of GY-511 is attached to pin SDA Pin of Arduino Uno and SCL Pin of GY-511 is connected to pin SCL in the Arduino Uno board. And the Output is being generated in Serial Monitor.
- The INT1 (Inertial Interrupt 1) and INT2 (Inertial Interrupt 2) is a Programmable interrupt, a 3.3-V-logic-level output. But it is not used in the circuit.
- The VIN Pin is for the 2.5 V to 5.5 V power supply connection. The SCL/SPC and SDA/SDI level shifters pull the I²C and SPI bus high bits up to this level. But this Pin is not used in the circuit.
- The Pin DRDY indicates Data Ready. It is an output that functions as a new data ready indicator. It is not used in the following circuit connection.
- This particular sensor measures the pressure or motion in the range of 10 ÷ 1200 hPa and temperature in the range of -40 ÷ 85 °C.

WORKING
Welcome to this Arduino based GY-511 Accelerometer and E-Compass Axis Magnetometer Sensor which mainly consists of 3 channel, 3 axis compass, magnetometer and an accelerometer. This magnetic sensor supports I2C protocols with standard and fast modes (100 kHz and 400 kHz), but does not support high-speed mode (Hs). External pull-up resistors are required to support the standard and fast modes. Depending on the application, the internal pull-ups may be used to support slower data speeds than specified by I2C standards.
The sensor module is supplied with both 5V and 3.3V voltage where 3.3V is considered ideal option. But if 5V is being supplied to the circuit, then pay special attention by connecting the sensor to the appropriate pin. The pin marked SCL (GY-511) is connected to the SCL pin (Arduino Uno), while the SDA pin (GY-511) to the SDA pin (Arduino Uno). The GND (GY-511) is connected with GND (Arduino Uno). Its major advantage is that it is 24-bit ADC converter which allows you to determine the height with an accuracy of up to 10cm on the basis of the pressure and motion measurement. But the ideal supply voltage lies in between 1.8V to 3.6 V with power consumption of just 1μA.
