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 ...

In infrared sensors, the semiconductor material plays a critical role in detecting light signals and converting them into electrical signals. SWIR sensors designed for advanced applications typically ...

Two recent announcements from developers of infrared sensors point the way towards new applications for thermal imaging systems, as the technology behind them continues to make rapid strides. At the ...

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 ...

As evidenced by the Covid-19 pandemic, quick and non-invasive techniques to assess body temperature have become necessary. In various locations, including hospitals, airports and schools, non-contact ...

Researchers at Northeastern University have developed a next generation smart sensor for the Defense Advanced Research Projects Agency (DARPA) that is capable of identifying infrared (IR) wavelengths ...

In this article, we implement a rain and ice sensor by analyzing the reflection of an infrared (IR) light source. This project uses proven techniques based on multiple reflections of IR light in the ...

Olympus has partnered with the Tokyo Institute of Technology to develop a new imaging sensor that is capable of capturing both color information and near-infrared information simultaneously. This is ...

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 ...

1. Measuring range. When choosing a sensor (pressure, temperature, analog, etc.), the measuring range should directly correspond with the physical measuring range in order to obtain the most accurate ...
