![]() ![]() The kit, with open-source Arduino sketch available, is a jump-start for putting up a programmable device/controller in vehicle or a vehicle data logger. We also designed several kits based on various types of Arduino boards, OBD-II adapter, GPS receiver and some dedicated parts (e.g. Later we also put accelerometer, gyro and temperature sensors into the adapter and make both OBD-II data and sensor data accessible via I2C. With the access to car data, some interesting applications can be carried out easily with Arduino and its rich resources. With developed Arduino library, it works as a data bridge between car’s ECU computer and Arduino as well as the power supply for Arduino and stacked shields or attached modules. Although originally not intended for the above purposes, commonly supported OBD-II data such as Vehicle Speed, RPM, and Fuel Level allow fleet tracking devices to monitor vehicle idling times, speeding, and over-revving.Įvolved from hobby projects, OBD-II UART Adapter was our first approach. The information it provides is commonly used by vehicle telematics devices that perform fleet tracking, monitor fuel efficiency, prevent unsafe driving, as well as for remote diagnostics and by Pay-As-You-Drive insurance. OBD-II is no longer only used by professionals and hobbyists to repair vehicles. ![]() The OBD-II port, equipped in most modern cars as a compulsory standard, opens up a gate to the inside of a car. A motor vehicle works as a closed systems for many reasons. The core of most vehicle telematics projects is the data, including vehicle ECU data, GPS data and some sensor (e.g. Practical applications of vehicle telematics include: Telematics, more specifically vehicle telematics, refers to the use of telecommunications and informatics systems within road vehicles. The goal of this project is to make it possible, accessible, and affordable for people, especially makers, to carry out vehicle telematics projects with open-source hardware, more specifically Arduino, the most popular single-board microcontroller platform designed to make the process of using electronics in multidisciplinary projects more accessible. The name of Freematics stands for Free (as in freedom) and Telematics. That’s why I started this project two years ago which is now named – Project Freematics. While developing and maintaining my video transcoding software, I am also an open-source hardware enthusiast, and at the same time very interested in vehicle telematics, which is basically about measuring my car’s performance and recording my driving history. ![]() For many years and till this day, I am the author of MediaCoder. ![]()
