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 ...

This infrared detector can be used to detect the presence of modulated infrared signals in its vicinity from any electronic source, for instance, an IR handheld remote controller. It can also be used ...

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 ...

Scientists from the University of Wisconsin-Madison (UWM) have developed a new type of material that can hide an object's heat signature from infrared sensors. The new material doesn't have a name yet ...

DALLAS, USA: Texas Instruments (TI) today introduced its next-generation wireless power transfer circuit with foreign object detection that will allow designers to bring to market 3-coil, 5-V and 12-V ...
