The circuit was designed to create a detection scheme with reference to light energy sources. Photo Detector – a device that detects and senses light and radiant energy which uses the principle of ...

Here is an interesting project circuit which is very useful in our real life. This circuit switches the street lights on detecting vehicle movement and remains off after fixed time.This can be used ...

Key Points Motion sensor lights help to save on energy by automatically turning the lights off when not in use.They are most effective for lights accidentally left on often, like outdoor lights and ...

The first room-temperature light detector that can sense the full infrared spectrum has the potential to put heat vision technology into a contact lens. Unlike comparable mid- and far-infrared ...

A single-photon detector (SPD) is sensitive to incidence of individual quanta of light and has many applications in photonics, such as fluorescence measurements, laser ranging, optical time-domain ...
