pair of IR Transmiter & Reciver (5mm)
Can be directly connect to a microcontroller, Arduino or Raspberry Pi with only a few current limiting resistors and require no complex circuit for getting it working.
Both the transmitter and emitter are built to work on the the 940 nm wavelenght.
Size: 5mm LED
Wavelength: 940nm wavelength (most commonly used)
100 mA continuous, 1000 mA pulse
Approx 1.6V forward voltage
Applicaitons: build wireless remotes for appliances, distance sensors, object sensors, colour sensors, line sensors, distance sensors, etc
Note: The transparent LED is transmitter while the dark blue one is the receiver.
