Aimed at industrial, medical, and commercial applications, the OPB720 is less expensive than traditional proximity sensors. The under-$35 plastic-packaged LED-photodetector measures 27.9 x17.3 x 8.4 ...

With increased automation of complex production systems, components that are capable of acquiring and transmitting information regarding the production process become necessary. Proximity sensors -- ...

[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors. The ...

Said to be the first device to combine an IR emitter, PIN photodiode, ambient light detector, signal-processing IC, and 16-bit ADC all in a 3.95 x 3.95 x 0.75-mm leadless surface-mount package the ...

Proximity sensors detect objects without physical contact. Most proximity sensors emit an electromagnetic field or beam and look for changes in the field. The object being sensed is called a target.

Elliptic Labs attracted a lot of attention at CES a couple of years ago when it demonstrated some pretty cool 3D gestural interactions based on ultrasonic wave technology. It allowed users to navigate ...

A device that detects the presence of an object in the vicinity. There are many types of sensors for myriad applications; however, they all work by emitting a signal and analyzing the changes in the ...
