This project is a laser-based security alarm system developed as part of my B.E. Electronics & Telecommunication Engineering coursework. It uses a laser beam and LDR sensor to detect interruptions and ...

This project uses an HC-SR04 ultrasonic sensor to measure how close an object is. A buzzer and LED react depending on the distance, similar to a car parking sensor. < 10 cm → buzzer and LED stay on.

Abstract: We theoretically propose and experimentally demonstrate a simple and compact approach for the first generation of multilongitudinal mode quadrature laser self-mixing (MQLSM) vibration sensor ...

Abstract: This paper presents a multifunctional wearable sensing system that integrates flexible Laser-Induced-Graphene (LIG) based sensors and an Open-Source Analog Front-End (AFE) chip. The LIG ...

The concept of a 3D scanner can seem rather simple in theory: simply point a camera at the physical object you wish to scan ...
