IR sensors rely on an emitter (IR LED) and a detector (photodiode or photoresistor) to measure infrared light and convert it ...

The BBA-4000 is a solar powered wireless infrared break beam system that is simple to install and requires no wiring. The break beam sensors are powered by lithium ion batteries that are recharged ...

Thermal infrared (IR) energy is emitted from all things that have a temperature greater than absolute zero. Human eyes, primarily sensitive to shorter wavelength visible light, are unable to detect or ...

This infrared alarm barrier can be used to detect persons passing through doorways, corridors and small gates. The transmitter emits a beam of infrared light which is invisible to the human eye. The ...

UK, March 12. 2024 - TAKEX AMERICA INC, a leading manufacturer of security sensing technologies, announces the launch of the PB-60TX, a next-generation photoelectric beam sensor designed for improved ...

It is critically important for instrument users to understand what the sensors in their instrument cannot properly measure, as well as what they can. Non-dispersive infrared (NDIR) sensors are ...

The iPhone 4S’s Siri feature has gotten a lot of attention over the past few weeks, but it seems like aspects of the way that Apple changed the new device to accomodate the voice-activated assistant ...

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 ...
