Ultrasonics refers to signals that are above the human hearing span (>20 kHz), and usually in the 40- to 70-kHz range. These signals are used like radar—they’re radiated toward a target and reflected ...

The sendEmail () function is responsible for triggering the email alert when an object is detected. A secure Wi-Fi client is ...

A small PlatformIO/Arduino project that measures distance using an ultrasonic sensor (HC-SR04 or similar) and prints the measured distance over the serial port. This README explains how to open the ...

Abstract: Target/object detection, recognition, position, movement speed, etc. is easy when the object is near or easily visible. But, the same doesn't stand true especially when the object is far or ...

ROS Laser Bot is a ROS Kinetic autonomous navigation project for TurtleBot using the Stage simulator and a Hokuyo laser model. It implements three smooth controllers—basic, advanced, and TF-based—to ...

Abstract: In this paper, we propose the use of ultrasonic sensors for autonomous parking systems. In general, LiDAR sensors are evaluated to be advantageous in autonomous parking systems, but this ...

Arduino has just announced the Arduino Matter Discovery Bundle (AKX00081), an all-in-one development kit designed to help ...

The system is built upon four foundational pillars: Autonomous Safety: Utilizing MQ-series gas sensors and flame detectors to provide real-time protection against fire and gas leaks through automated ...
