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 ...

Proximity sensors that use ultrasonic sound waves calculate distance to an object using the time it takes to receive the echo from an ultrasonic burst. But, similar bursts from other sensors in close ...

For years, ultrasonic sensors have been used in a wide range of applications including fish finders, parking sensors in cars and burglar alarms. In this article, we describe the characteristics of ...

One of the biggest mistakes Tesla made last year was removing ultrasonic sensors from the cars without offering an alternative. With the 2022.45.11 software update, cars without ultrasonic sensors ...

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 ...

A low-cost (~$100), do-it-yourself (DIY) ultrasonic water level sensor/datalogger has been designed, constructed, and tested for use in education, citizen/community science, and research settings. The ...

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 ...

Chirp Microsystems’ CH-201 MEMS sonar-on-chip time-of-flight (ToF) sensor offers a sensing range of up to 5 meters for room-scale applications. Expanding the SmartSonic MEMS ultrasonic platform, the ...

[Emil] got his hands on a dozen HC-SR04 ultrasonic sensors, but wasn’t too happy with their performance. Rather than give up, he reverse engineered the sensor and built an improved version. Hackers, ...
