This is a project circuit which helps to a person in the driving seat and gives an alarm if there is any obstacle or a wall while parking or while driving in reverse. This is a project circuit which ...

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 ...

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 ...
