Photo sensor working
WebPhotodetector. Photodiode. Photodetector is a photosensor. It is a light-sensitive semiconductor diode. The photodetector is not used with an amplifier to detect the light. The photodiode uses an amplifier for detecting low levels of light as they permit a leakage current that changes with the light that falls on them. WebDec 30, 2024 · PIR sensors are mainly used in PIR-based motion detectors. How does an infrared sensor work? An infrared sensor works the same way an object detection sensor does. The sensor typically has an IR LED & an IR photodiode, and combining these two gives way to a photo-coupler or optocoupler.
