There is a point where taking technology for granted hides some of the incredible capabilities of seemingly simple devices. Optical mice are a great example of this principle, using what are more or ...

This project involves using an Arduino to measure distances using an ultrasonic sensor and controlling a buzzer and LED based on the measured distance. The provided Arduino code performs the following ...

I purchased one of each of these cheap sensors recently from aliexpress for testing purposes. Compared with the ubiquitous HC-SR04 (*), I liked the idea of having a combined emitter/receiver, i.e.

After reading the CNXSoft article "Arduino launches Modulino Hub and Extender modules to support up to 64 I2C devices, 30-meter range", I learned that Arduino has released official peripheral modules ...

Abstract: This letter presents a novel method for distance variation robustness enhancement of microwave resonator-based sensor using artificial intelligence. Since any small change in the distance of ...

We present a single piezoelectric micromachined ultrasonic transducer (PMUT) sensor that unifies proximity ranging and contact detection toward fingertip integration. Proximity is obtained by ...
