Distance and Proximity

This lab explores long-range distance measurement using a sonar sensor, mid- to short-range distance measurement using a Time-of-Flight sensor, and proximity measurement using an infrared proximity sensor. Students complete hands-on activities involving sensor calibration, measurement scatter, and target reflectivity.
