The Arduino reads these acceleration values from the sensor and then calculate the pitch and roll values using the functions provided by the MPU6050 library.
This change in capacitance is measured and corresponds to the acceleration value. So, when acceleration is applied in any direction, the capacitance between the plates and the mass will change. Its structure has a mass attached to a spring which moves along one direction and has fixed outer plates. The accelerometer sensors measure the acceleration by measuring the change in capacitance. We can give 5V input because the sensor module has a voltage regulator for converting the 5V input into 3.3V The accelerometer sensor range is ☒, ±4, ☘, ☑6g.The specifications of the GY-521 MPU6050 are as follows The breakout board has a voltage regulator for converting the voltage level from 5V to 3.3V and also has an InvenSense MPU6050 chip which holds the accelerometer and gyro meter sensors. XDL (Auxiliary data line): Responsible for the Auxiliary I2C communicationĪDO: Responsible for slave or master interface
XCA (Auxiliary clock line): Responsible for the Auxiliary I2C communication SDA (Serial data line): Responsible for the primary I2C communication SCL (Serial clock line): Responsible for the primary I2C communication The GY-521 breakout board has a total of 8 pins which are as follows: The DMP unit is responsible for combining the raw data and performing some calculations to remove the errors in each sensor.
The chip also includes a 16-bit analog to digital converter on each channel and a DMP (Digital Motion Processor) unit. This makes it a 6 DOF IMU (6 degrees of freedom inertial measurement unit). The GY-521 has an InvenSense MPU6050 chip which contains a 3-axis accelerometer and a 3-axis gyro meter. rtiostream_utils.In this article, we are going to interface the GY-521 accelerometer with Arduino.
