When light strikes the photodiode’s active region, current flows from cathode to anode. Ideally, this entire photocurrent ...

Researchers at the University of Illinois have pulled off a laser first: they built a new kind of eye-safe laser that works ...

Overall world revenue for the Military Electro-Optical and Infrared (EO/IR) Systems Market: In terms of value the market will surpass US$13.87 billion in 2025, the work calculates. The publisher ...

Normally these speed sensors work with radar or laser technology to bounce back radio waves or IR light from objects and calculate speed based on time taken for the light or wave to reflect. In this ...

It just uses an IR LED and some fancy optics. How it Works The simple explanation for how these sensors work is that they bounce light off a target and measure how long it takes to see the reflection.

We explain radar, sonar, cameras, and lidar sensors, plus the magic that brings all of their data together.

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 ...

Arduino simplifies things by only using just one coding language. Here's what you need to get started with developing software for the tiny device.

Here’s an explainer on how it works and how to use it. Google Pixel 8 Pro temperature sensor Google Pixel 8 Pro comes with a contactless temperature sensor on the camera visor.

Google Nest Protect: $119 CO2 sensor What it measures: These use infrared sensors that measure light in the air, because this is inversely proportional to the amount of CO2.
