[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.

[Klaus] wanted some sort of aid for parking his car, and after running across a $4 ultrasonic sensor, decided to build his own speaking distance sensor (.de, Google Translation). Inside [Klaus ...

Our process allows the physical proximity between sensors and computing elements to be reduced to 50 nm, providing reduced latency in near-sensor computing applications." A key advantage of the ...
