Vishay Semiconductors has created an interesting reflectance proximity detector (VCNL4000) that includes an infrared (IR) LED and a photodetector. A second sensor in the same package measures ambient ...

Tagging wildlife is never straightforward in the best of times, but it becomes a great deal more complicated when you’re trying to track flying insects. Instead of trying to use a sensor package, ...

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 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 ...

In the race to create the world’s first self-driving car, new ADAS (advanced driver assistance systems) – such as a low-cost (light detection and ranging) LIDAR detection system developed to meet 2018 ...
