I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

Agile Analog has added a customizable IR drop sensor to its IP library, providing chip designers with real-time monitoring of voltage drops. These drops can be caused by power supply fluctuations, hot ...

For Part 1, click here. High-speed optical communications applications have some high-level transimpedance-amplifier (TIA) circuit similarities with laser rangefinders (LRFs) and LiDAR. However, there ...

Substantial miniaturization of infrared (IR) sensors is necessary for their incorporation into next-generation portable electronics, wearable devices, and small satellites. However, modern infrared ...

As radar technology continues to advance, it offers an increasingly broad range of capabilities, making it a viable alternative to traditional passive infrared (PIR) sensors. With radar’s enhanced ...

Members can download this article in PDF format. Light sensors detect the presence or absence of light, and the intensity of that light. These sensors then convert light energy into an electrical ...
