optical sensors

Photon-sensing devices

Optical sensors are devices that detect and respond to light, converting light energy into electrical signals for measurement or processing.

They range from simple photodiodes that sense brightness to sophisticated camera systems and barcode readers.

Optical sensors appear throughout modern technology—in smartphones detecting ambient light, in motion detectors, and in industrial equipment monitoring production lines.

The optical sensor adjusts screen brightness automatically.
