Python-OBD is a library for handling data from a car's On-Board Diagnostics port (OBD-II). It can stream real time sensor data, perform diagnostics (such as reading check-engine codes), and is fit for the Raspberry Pi. This library is designed to work with standard ELM327 OBD-II adapters.

Install the latest release from pypi:

$ pip install obd

If you are using a bluetooth adapter, you will need to install the following packages:

$ sudo apt-get install bluetooth bluez-utils blueman

import obd

connection = obd.OBD() # auto-connects to USB or RF port

cmd = obd.commands.RPM # select an OBD command (sensor)

response = connection.query(cmd) # send the command, and parse the response

print(response.value)
print(response.unit)
