Abstract: This paper provides an overview of balanced (or differential-mode) structures operating at microwaves, including common-mode suppression filters, balanced filters and circuits with intrinsic ...

The device uses an ultrasonic sensor to detect nearby obstacles and provides real-time audio feedback, helping users navigate their environment more safely and independently.

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: Mass production of widely used semiconductor digital integrated circuits (ICs) has lowered unit costs to the level of ordinary daily consumables of a few dollars. It is therefore reasonable ...

In this Arduino Project, you will also learn how to build an Arduino smoke alarm that sends SMS Alerts without needing to rely on the GSM module. The Arduino UNO R4 will detect fire or smoke using the ...
