IR INTRUDER CKT: Infrared LED & Phototransistor Pair 5mm


Pair of Infrared LED and Photo diode tuned to IR wavelength

IR Transmitter & Receiver Pair
Use this 5 mm ir transmitter and receiver pair to build object sensors, color sensors, line
sensors, distance sensors, etc. Both the transmitter and receiver are built to work on the
940 nm wavelength.

Note: the transparent led is transmitter while the dark blue one is the receiver.
