If you have one ultrasonic sensor and a microcontroller, you can detect plenty of useful things, like the water level in a rain barrel or the distance traveled by a tablet along a rail.

The quick road test, oh it’s a simple approach to display the distance measurements on the Arduino Serial Monitor. I will use this sensor (or its latest version) in a more complex project in the next ...

Arduinos are great microcontroller boards with plenty of interesting features, but they can't do much without additional components. There are loads of unique sensors available on the market for ...

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 ...

But the ultrasonic sensor can do even more. It is so accurate and precise that it even registers when molecules of other ...

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 ...

Inductive sensors are non-contact proximity sensors that detect ferrous targets, ideally ones made of mild steel thicker than one millimeter. They consist of four major components: a ferrite core ...

The range now includes ultrasonic proximity sensors and fibre optical sensors which join the photoelectric proximity sensors (through-beam, retro-reflective and diffuse), inductive proximity sensors ...

Of course, improvement to the sensors and pressure/distance equations might help, too. Advertisement “We made this entire suit using parts you can buy off DIY websites,” writes Brad Haggadone ...

I have seen too many posts highlighting the erroneous distance reports of the HC-SR04 ultrasonic sensor module. In principle, it can “conditionally” detect the distance of objects between 2 and 400 ...
