Fujitsu has developed a high-sensitivity and high-resolution infrared sensor to expand monitoring capabilities in the defense and disaster prevention fields. This sensor is a Type-II superlattice ...

A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors.

Prof. Jong-Soo Lee’s team realizes a “hybrid photosensor” combining quantum dots and two-dimensional semiconductors - ...

Electro-optical detectors are used to measure or sense the radiation emitted or reflected by objects within the detector’s optical field of view (FOV). Passive systems operate without any illumination ...

We all know that feeling: you've turned the lights off and are almost asleep when you hear that infamous buzz. A mosquito is hunting in your bedroom. The dance commences. You could turn on the lights, ...

The sensor/monitor shown in the diagram ‘wakes up’ the host system on detection of infra-red (IR) signals. It draws so little supply current that it can remain on continuously in a notebook computer ...

Invisible infrared waves are emitted by IR LEDs and detected by photodiodes to enable devices like remotes, automatic ...
