The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

This ultrasonic radar project is from [mircemk] who uses a small ultrasonic distance sensor attached to a rotating platform. A motor rotates it around a 180-degree field-of-view and an Arduino ...

The sensor shown here is essentially two plates mounted side-by-side, attached to an Arduino Nano using the Capacitor library which uses just two pins, one digital and one analog.

Lidar tells distance, radar tells velocity, this new sensor aims to do both A new sensor startup has just come out of stealth mode. Timothy B. Lee – Sep 21, 2017 10:35 am | 93 ...

A lot of new cars have fancy cameras on the rear bumper to help you parallel park. If your car doesn't have that feature, DIY blog Mad Science has put together a tutorial to roll your own sensor ...

Over a certain range of reflected amplitudes, this reflection pulls the frequency of the oscillator, swinging it between 234.9 and 235.1GHz depending on the phase of the return. Frequency varies ...
