Sub-$20 Arduino-Based Telemetry System

Sub-$20 Arduino-Based Telemetry System

[William Osman] set out to prove that unlike expensive commercial data logging rigs, he could get the same results for under twenty bucks . He wanted to build a wireless three-axis accelerometer for a race car project, allowing engineers to make modifications to the suspension based on the data collected. The hardware consists of an Arduino Pro Mini connected to a three-axis accelerometer, and an nRF24L01 wireless module. Power is supplied by the race car’s 12 V, changed to 5 V by a linear regulator with the Pro Mini in turn supplying 3.3 V. The base station consists of an Arduino and another nRF24L01 module plugged into a laptop. The telemetry system is based on COSMOS , an open-source, realtime datalogging platform put out by Bell Aerospace. COSMOS consists of fifteen separate applications depending on how you want to view and manage your telemetry. You can download [Wil...
