This infrared detector circuit uses a passive IR-detector component PID20. It converts heat radiation into electrical impulses. The output voltage of the PID20 increases when an object comes close to ...

Scientists have discovered a potentially promising infrared LED and infrared detector component. This compound -- composed of calcium, silicon and oxygen -- is cheap to produce and non-toxic. Many of ...

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

Researchers at the University of Turku, Finland, have developed an organic infrared photodiode that achieves record-level sensitivity in devices that are ultrathin and ready to be integrated into ...

Sandia National Laboratories optical engineer Michael Goldflam sets up equipment to load and characterize a new nanoantenna-enabled detector. A team of researchers at Sandia National Laboratories has ...

For decades, bulky spectrometers have been the main tools for understanding how things are made of chemicals (a thing called composition). Spectrometers are a type of lab equipment that uses prisms or ...

A car full of people can soon lead to the build-up of CO 2 to a level where the driver can be come drowsy, creating a safety issue. Of course, it is possible to ventilate the cabin all the time but at ...

Sensor from German-Italian group makes visible two key ranges of infrared not previously revealed by regular photodiodes. Images of San Francisco Bay in visible light (l) and shortwave infrared (r).

The project aims to build a very simple clock that does not contain any buttons, alarms, or settings besides time as it uses infrared to detect light. The IR sensor data is being read by the ...

Many robotic applications require a sensor to detect close or very close obstacles. Typically, reflective-type infrared sensors are used for this task. But the circuit in the figure shows an infrared ...
