Photoelectric sensors detect objects and surface changes using variations in optical properties. Each sensor includes a light emitter and a receiver, with most relying on infrared light. In optical ...

The purpose of this research is the design of the water clarity monitoring system in the aquarium can detect the level of clarity/turbidity of water at a certain level, using Arduino Uno ...

A 0.25 /spl mu/m technology CMOS image sensor employs a 4.2 /spl mu/m pitch pinned-photodiode pixel. A column amplifier and digital domain processing reduce the fixed pattern noise to 55 /spl mu/V.
