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 ...

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 sensor package comprises an ultrasonic distance sensor, a microcontroller running Arduino firmware, a micro-SD card for datalogging, a real-time clock for timekeeping and sleep functions, and an ...

An Arduino polls the ultrasonic sensors and provides feedback via the boxes. This completely frees up the user's hands for other tasks. Advertisement. While the prototype has a ways to go, such as ...

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 ...
