Road-Condition-Acquisition

Data acquisition on the condition of roads with the use of Raspberry Pi. This is a part of two-part project, have a look at the data analysis module here: https://github.com/Dheeraj1998/Road-Condition-Analysis

Interfacing Raspberry Pi and MPU-6050

How to Setup the device (Rasbian OS)

It's an I²C board so first you need to install the relevant Linux drivers.

• Open the file for editing (needs sudo)

sudo vi /etc/modules

• Add the following lines to the bottom of the file, save it and reboot the Pi

i2c-bcm2708
i2c-dev

• Now check the blacklists file

sudo vi /etc/modprobe.d/raspi-blacklist.conf

• Make sure that the following lines if present start with a # (Lines are commented) , if not nothing to worry

#blacklist spi-bcm2708
#blacklist i2c-bcm2708

Connecting the Sensor

We will make use of GPIO pins to make the connections with Pi The pins to be connected are

• Pin 1 - 3.3V connect to VCC
• Pin 3 - SDA connect to SDA
• Pin 5 - SCL connect to SCL
• Pin 6 - Ground connect to GND

Verifing the Connections

For testing if the Pi has detcted the board connected. Following copmmands are used to install the i2c tools

• Step 1

sudo apt-get install i2c-tools

• Step 2 (For Revision 1 board)

sudo i2cdetect -y 0

• Step 2 (For Revision 2 board)

sudo i2cdetect -y 1

We need to install the smbus module to read from the I2C using Python bus

• Installation Command

sudo apt-get install python-smbus

Congrats, we are done!

Now execute the above code to check if we are getting the correct data.
