5mm 940nm Infrared Receiver Photodiode (IR Sensor)

The 5mm 940nm Infrared Receiver is a light sensitive semiconductor device designed to detect infrared radiation and convert incident light into an electrical response. It is intended for optical sensing applications where infrared transmitters and receivers work together to detect objects, measure interruptions or monitor reflected light.

The exact device type is important because a photodiode and a phototransistor have different electrical characteristics and output behavior. Confirm the component datasheet before selecting the appropriate interface circuit.
