Sonair, a sensor technology company in Oslo, Norway, is set to debut its ADAR (Acoustic Detection and Ranging) sensor to North American audiences at Automate 2025 next week in Detroit. Designed to ...

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 ...

In this review of the Maker Uno RP2040 board with the Arduino IDE we could blink LEDs, control RGB LED lights, press the user button to turn on one LED or make the buzzer output some melody, control a ...

In response to these limitations, this research endeavors to design and implement a radar system using Arduino microcontrollers and ultrasonic sensors. This innovative approach leverages the ...

Ultrasonic sensors offer several benefits, including very accurate object detection, high refresh rates, and low cost for IoT applications.

Amazon Echo’s built-in ultrasonic motion sensing can let you easily automate lights and fans with Alexa routines, without buying anything else.

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.

Now, as we know how the components work, let’s go ahead and assemble theses components together and make a circuit as shown below. The Ultrasonic sensor is powered by 5V through Arduino, its trigger ...
