Python-OBD
A Python module for reading real-time sensor data from OBD-II vehicle ports using ELM327 adapters.
What is Python-OBD?
python-OBD is a Python module for interfacing with OBD-II vehicle diagnostic ports to read real-time engine and sensor data. It connects to ELM327-based adapters and provides a simple API for querying parameters like speed, RPM, temperature, and fuel levels. The library handles unit conversions and protocol differences, making it accessible for automotive telematics and monitoring applications.
Developers, hobbyists, and researchers working on automotive telematics, vehicle monitoring systems, or Raspberry Pi-based projects that require access to real-time vehicle data.
It offers a pure-Python, well-documented solution with extensive OBD command support and unit-aware measurements, eliminating the need to deal with low-level serial protocols. Its compatibility with affordable ELM327 adapters and Raspberry Pi makes it a cost-effective choice for DIY and professional applications.
