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

The rise of infrared AEB, with automotive infrared night vision experiencing a 384.7% year-on-year increase from January to September. From Janua ...

Automatic Soap Dispensers designed for use with liquid soap are now widely available, and you may well know that the hands free operation reduces the spread of germs. How about building one your own?

Unlike infrared optical sensors that use an LED transmitter and IR receiver, the PIR emits nothing. As its “passive” name suggests, it responds only to infrared energy radiated by the object being ...

[ladyada] has a freshly-published and amazingly thorough tutorial on passive infrared (PIR) motion sensors. Most often seen in security floodlights and automatic doors, in creative hands these sensors ...

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 ...

I needed a multichannel line tracker sensor module for an upcoming project. A quick search found several versions of infrared line tracker sensor modules that met or exceeded my demands, but I picked ...

Some readers may recall building a line-following robot during their school days. Involving some IR LEDs, perhaps a bit of LEGO, and plenty of trial-and-error, it was fun on a tiny scale. Now imagine ...

The F-22 will receive an embedded set of TacIRST sensors as part of the Infrared Defensive System to enhance aircraft survivability and lethality. Lockheed Martin announced on Jan. 22, 2025, that it ...

A reusable sensor for in-line glucose monitoring, believed to be the first of its kind, has been launched by Hamilton Company.
