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 ...

Photodiodes are used in a wide variety of applications to transform light into a current or voltage. These range from solar cells to optical data networks, from precision instruments to chromatography ...

In this section we shall discuss the interface between a photosensor and its associated electronics. There are really just two photocell applications – light measurement, and the reception of ...

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 ...
