In order to help his friend prepare for a talk at DEFCON this weekend, [Craig] built an IR photodiode amplifier circuit. The circuit extended the detection range of the hack from a few inches to a few ...

Although advances in photonics and electronics are making it easier and cheaper to implement a light detection and ranging (LIDAR) system, the analog front-end receiver interface still presents many ...

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.
