But the circuit in the figure shows an infrared close-object alert system built aroun Many robotic applications require a sensor to detect close or very close obstacles. Typically, reflective-type ...

It can also be used for testing infrared burglar alarm systems. This is not an infrared motion detector! The IR detector circuit in principle, converts the IR signal pulse trains into noticeable aural ...

This improved infrared detector is specifically intended for use with commercial IR remote control handsets. This little circuit is useful for quick go/no-go testing of just about any remote control ...

Researchers traced long, bright radio pulses, combined with X-rays, to an intriguing cosmic object 15,000 light-years from ...

and IoT devices that typically use passive infrared (PIR) sensing. The STHS34PF80 sensor contains thermal transistors that can detect stationary objects, unlike conventional PIR detectors that ...

If you want to test drive your newly constructed detector but don’t have an IR source within reach, the next circuit should help you out. It too implements a 555 timer IC, but instead of driving ...

There is another way to decrease the temperature of an object—and it doesn't ... region of the electromagnetic spectrum infrared light. You can't detect it with your eyes, but we can produce ...

Hotter objects typically glow brighter than cooler ones, making them stand out in infrared images ... for instance, or to detect sources of heat behind thin walls. For now, the high temperatures ...
