Sometimes, it’s time to shut down the oscilloscope, and break out the cardboard and paints. If you’re wondering what for, well, here’s a reminder of an Instructable from [CrazyScience], that brings us ...

A salvaged Tesla Model 3 could detect distances even after the front bumper containing the ultrasonic sensors was taken off. This finding is surprising considering that the car was running the 2022.28 ...

Valeo has been granted a patent for an ultrasonic sensor designed for vehicle distance detection systems. The sensor can be installed with others, receiving and modulating data signals through supply ...

Tesla removed the ultrasonic sensors from the recently-built cars in a move many framed as a cost-cutting measure. Without them, some parking features and distance measurements to obstacles around the ...

There is a lot of buzz about electromagnetic (EM) detection and ranging sensor technology, which encompass radar, lidar, infrared (IR), ultra-wide bandwidth (UWB), and many others. However, there are ...

As the world struggles with the impact of COVID-19, businesses and governments are seeking ways to safely restart global commerce and local economies to mitigate the financial impact of the virus.

Makers, developers and enthusiasts building distance related projects may be interested to know that the HC-SR04 ultrasonic sonar distance sensor is now available to purchase directly from the ...
