This pair of 3mm IR High-power directional IR LED and Filtered photodiode can be used in various kinds of sensing circuits. The narrow beamwidth IR LED emits focused IR light and the filtered photodiode filters out ambient light without the need for any external circuit. When used with a proper circuit it can give up to 200 mm of reflective sensing and can also be used in high-speed applications like encoders.
It has a peak wavelength of 940nm.IR sensors are also used in IR imaging devices, optical power meters, sorting devices, missile guidance, remote sensing, flame monitors, moisture analyzers, night vision devices, infrared astronomy, rail safety, etc.
Applications of IR Transmitter & Receiver Pair:
IP cameras
Gas Analyzers
Alarm systems and other crime prevention devices
Battery-driven human presence sensors for IoT smart homes
IR sensors are also used in IR imaging devices, optical power meters, sorting devices, missile guidance, remote sensing, flame monitors, moisture analyzers, night vision devices, infrared astronomy, rail safety, etc.
