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 ...

This project demonstrates an Arduino-based Human Following Robot using IR sensors and an ultrasonic sensor. The robot detects a human presence in front of it and follows smoothly while correcting its ...

Abstract: Radar technology has been a cornerstone of numerous applications, from aviation to meteorology, offering invaluable capabilities for object detection and tracking. Traditional radar systems, ...

Hello Hackers! Today we have a really interesting topic. Searching the internet, I didn't find any simple solution on "How to read data from car parking sensors," so I decided to write a short and ...

Abstract: Ultrasonic distance estimation sensor and Lidar micro sensor have been employed in the proposed obstacle detection and collision avoidance method for the computation of the distance between ...

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

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 ...

The MAX471 is an older current sensor which can handle up to 50 Watt, with a maximum of 25 Volts or a current of 3 Amperes. It is officially not supported any more however there are still many for ...
