IR infrared speed sensing module

Took less than five minutes to wire into my two-wheeled car’s motor shaft, and the IR beam picks up each rotation cleanly even at low speeds. The response is instant and steady, which made tuning the PID loop way easier than I expected.

Worked perfectly out of the box on my 4-wheel smart car, and the IR sensor picks up the wheel spokes cleanly even at low speeds. Took me about ten minutes to get the mounting right, but the response is instant once calibrated.

Finally got this hooked up to my 2-wheeled smart car and the IR beam is so clean it picked up every single rotation of the motor. The response time is noticeably faster than the old hall-effect sensor I was using.
