ESP32 motion detection setup with Arduino and ESPHome for Home Assistant
In this video, I'm exploring the use of Mini PIR Sensors with ESP32 with both Arduino-based projects as well as making a movement sensor for Home Assistant by using ESPHome. The sensor is quite ...
Exceptional points (EPs) in non-Hermitian systems offer a strong response to perturbations, offering a promising platform for sensing. By using a third-order EP of coherent perfect absorption, here, ...
Abstract: This paper provides details about the design and operation of a Collision Avoidance System in smart cars, with the Arduino board as the central control unit, interfaced with an ultrasonic ...
