You might wonder if a tiny plastic component is worth the space on your workbench, but these Adafruit IR sensors prove that size isn't everything in robotics. These miniature modules use a simple two-element system—an IR LED and a phototransistor—to detect reflectivity by bouncing light off nearby objects. They are absolute lifesavers for building compact line-following robots because you can solder them incredibly close together without interference. While you will need to provide your own resistors for the LED and pullup, the inclusion of five sensors in one pack makes them a great staple for any hobbyist kit. They perform most reliably when detecting light colors at about 5mm, making them perfect for high-speed RPM sensing or simple proximity detection.
