An optical sensor is generally part of a larger system that integrates a source of light, a measuring device and the optical sensor. This is often connected to an electrical trigger. The trigger reacts to a change in the signal within the light sensor.

A photoresistor (or light-dependent resistor, LDR, or photoconductivecell) is a light-controlled variable resistor. The resistance of a photoresistor decreases with increasing incident light intensity; in other words, it exhibits photoconductivity. A photoresistor can be applied in light-sensitive d..
A photodiode is a semiconductor device that converts light into an electrical current.
The current is generated when photons are absorbed in the photodiode. A
small amount of current is also produced when no light is present.
Photodiodes may contain optical filters,
built-in lenses, and may hav..
