COSMOS and Arduino: The $20 Telemetry System

I built an inexpensive, PC based, wireless telemetry system using COSMOS and Arduino. This system measures 3-axis accelerations of a race car allowing engineers to verify and tune the suspension design.

Data acquisition is an integral part of the engineering process. Automated data collection, processing, and presentation will streamline design iteration and reveal previously undetectable issues. Simply watching your design function correctly isn’t an indication that it’s functioning efficiently.

The problem with telemetry is it’s difficult to build and expensive to buy. Professional solutions like LabView and associated DAQ (data acquisition) hardware cost thousands of dollars. Open source hardware like Arduino and its large community make data collection easy, but doesn’t solve the data presentation.

An incredibly inexpensive, dynamic, and expandable telemetry system can be built using Arduino and COSMOS. “
