[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 GP2Y0D02 is an infrared proximity sensor with a detection field that ... The open collector output overcomes the small amount of current flowing through resistor to register the low state.

A new string spotted in iOS 4.3 reveals that Apple may be sweating the small stuff to perfect the user experience ... The current iPad does have an ambient light sensor, but the proximity sensor would ...

Examples of these devices include infrared thermometers and vehicle proximity notification systems. One type of non-contact sensor relies on static electricity to detect closeness and small ...

Thanks to its magnetic-field detection in X, Y, and Z directions, Diodes Inc.’s automotive-qualified AH4930Q is able to ...
