All,
I'm working with my local high school on a project for their race car, a single-seat electric go cart. The project is a data logger and measures car performance, records to an SD card and sends data to the pit crew for live analysis. It's very cool and works like a million bucks. The data logger and pit display are based on a Teensy 3.2.
Next step is to have the data logger automatically track laps--and here's where we're stuck. We don't want to rely on the driver or pit to record laps hence some automatic way. I can live with +/- 5 to 10 feet accuracy in when a lap is considered a lap.
Thought 1 was to have some beam of light by the track and a sensor on the car that will trigger LapCount++; but i for safety I want to avoid anything visible. Maybe an infrared light but not sure about the range of a light source.
Thought 2 we to have the data logger listen to an inaudible sound but that will be highly inaccurate.
Thought 3 is to connect a GPS sensor and look at longitude and latitude with a tolerance.
For a view of our conditions, fast forward to the 29 minute mark to see what the track looks like. Also look at the readout by the cars steering wheel. Maybe seeing the car and track will gel some ideas.

Thanks in advance.
