🛠️🌍 Wi-Fi controlled four-wheeled scout vehicle using dual Arduino Uno R4 boards, ultrasonic sensor, turret rotation, and LCD display for real-time obstacle detection.

Magnetic nanomaterials (MNMs) have gained great interest from different fields of study ranging from wastewater treatment to (bio)sensor development, taking advantage of both nanoscale size (allowing ...

Water level monitor using open-source microcontrollers (Arduino, ESP8266, ESP32) and ultrasonic sensors HC-SR04 / JSN-SR04T and similar with Trigger and Echo signals. Arduino Core & ESP-IDF ...

Abstract: We present a low-power gas sensor design based on a capacitive micromachined ultrasonic transducer (CMUT), for use on self-powered wearable platforms. Earlier a CMUT-based sensor, with 70-mW ...

We propose a micro-ultrasonic diagnosis using an all-optical ultrasound-based spectral sensing (AOUSS) technique for sensitive and quantitative characterization of early stage and whole blood ...
