Follow these seven steps to successfully select a photodiode sensor and design an analog front end for a range of applications such as optical communications and light-based measurements. The energy ...

This Circuit can compare the Light level in an area. It uses a PN Photodiode as the light sensor and IC CA3140 as voltage comparator. The circuit is ideal as the front end of burglar alarm circuits.

Sensors are energy conversion devices. Sensors or transducers convert the physical world of light, pressure, temperature, flow, level, acceleration, force, etc. to electrical signals but generally ...
