Researchers have developed a highly sensitive method for detecting hotspots in the environment, such as bushfires or military threats, by harnessing the focusing power of meta-optical systems.

IR sensors rely on an emitter (IR LED) and a detector (photodiode or photoresistor) to measure infrared light and convert it into electrical signals. There are two main types of sensors: ...

There may soon be a new infrared detection sensor on the market that can better scrutinize friendly forces on the ground and shrink the time it takes to identify targets of opportunity. UTC Aerospace ...

Lockheed Martin to equip two Apache battalions with low-light sensors, while FLIR will provide the US Army with 36 SAFIRE night vision systems. While the Pentagon looks to make cuts to US military ...

The last 10 years or so have produced some colossal and deadly fire events that have destroyed whole towns, burned a record amount of acreage, and polluted skies for weeks. And wildfires are not just ...

LONDON--(BUSINESS WIRE)--Technavio has announced the top five leading vendors in their recent global military electro-optical and infrared (EO/IR) systems market report. This research report also ...

In the last decade the number and intensity of forest fires seems to have been on the increase around the globe, with massive and devastating wildfires in California, Greece, Russia and Australia. The ...

Since its founding, LASER COMPONENTS has specialised in IR sensors for use in fire detection devices. We manufacture both lead sulphide and pyroelectric detectors at our assembly plant in Tempe. A ...

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 Australian jewel beetle Merimna atrata has several heat sensors. Originally it was thought that it uses them to detect forest fires as the insect lays its eggs in the wood of burned eucalyptus ...

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 ...
