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 ...

Instead, it relies on an ultrasonic distance sensor to detect a hand (or foot) waved in front of the door. An Arduino Leonardo runs the show, sounding a buzzer when the ultrasonic sensor is triggered.

Ultrasonic sensors are cheap enough to hack into other things, like this one-way data communications module. ... Everything is contained in a water-resistant box and driven by an Arduino Pro.

In this mode, you can interface the HC-SR04 ultrasonic ping sensor with a servo motor and the main board (Only some reward tiers include the extra servo motor PCB and servo motor kit).

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 ...

Fraunhofer researchers will present their development at the SENSOR+TEST measurement fair in Nürnberg, May 30 to June 1, 2017. Technical systems must be regularly checked for defects, such as cracks.
