Interfacing an MPU6050 IMU Sensor with Raspberry Pi

Updated: Feb 12

The MPU6050 is an IMU(Inertial Measurement Unit) sensor that comes with an Accelerometer, Gyroscope sensor, and a temperature sensor too. It consists of a MEMS accelerometer, a temperature sensor and a MEMS gyro. When converting analogue values to digital, this device is very precise because it has a 16bit analogue to digital converter hardware for each channel. This module is capable of capturing channels x, y and z simultaneously. For interact with the host controller, it has an I2C interface. For many applications, such as drones, robots and motion sensors, this is a very useful unit. It is sometimes referred to as the Triple Axis Accelerometer or Gyroscope.

List of components required:

1. Raspberry Pi

2. MPU-6050

3. Jumping wires

4. Breadboard


Raspberry Pi: The Raspberry Pi is a series of small single-board computers which was developed by the Raspberry Pi Foundation in the United Kingdom. Early on, the Raspberry Pi project focused on encouraging basic computer science teaching in schools and in developing economies. The original design later became much more popular than expected, selling for uses such as automobiles outside its target group.

MPU-6050: The MPU 6050 is a 6 Degrees of Freedom or a six-axis IMU sensor, which means that it produces six values. Three values for the accelerometer and three for the gyroscope. The MPU 6050 is a MEMS (Micro Electro Mechanical Systems) based sensor.

Jumping wires: Jumper wires are essentially wires with connector pins at either end, allowing them to be used to connect two points to each other without soldering. Jumper wires are usually used for breadboards and other prototyping instruments to make it easy to adjusts circuits.

Breadboard: The breadboard is a rectangular acrylic board with a tonne of tiny holes inside it. Such holes allow you to quickly insert electronic components into the model of an electronic circuit, such as this one with a battery, a switch, a resistor, and an LED.

Circuit diagram

In #MPU6050 we have 8 eight pins on them in that 8 pins we VCC, SCL, ground and SDA evidence. Now we will setup i2c communication format with the raspberry pi board here VCC is connected to the 5-volt pin, ground is #connected with ground, SCL with SCL pin and SDA pin with SDA pin on the raspberry pi. This sensor can we used to measure velocity, rotational velocity and many other parameters.


Code:



Working:

In-circuit #diagram we have already gone through connections with the help of bread we connect MPU 6050 sensor with #raspberry pi board through jumping wires.

Working

The above picture is after switching on power to raspberry pi. If we observe #LED lights are switched this shows that power supplied throughout the #circuit.
