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 ...
The sensor allows non-contact monitoring of moving objects with temperatures from 250 to 1250 ºC (482 to 2282 ºF) or in inaccessible or harsh environments. Units are available with 4-20 mA interface ...
