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 ...

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 ...

Default value for maximum measurement distance is 4m, since HC-SR04 sensor can't measure reliably beyond that. However, if you are using another sensor or if you you don't care about distances larger ...

Abstract: A fully integrated 3-D ultrasonic fingerprint sensor-on-a-chip is presented. The device consists of a 110× 56 piezoelectric micromachined ultrasonic transducer (PMUT) array bonded at the ...

Abstract: Ultrasonic sensors are able to provide highly accurate measurements if they are properly scheduled, otherwise, the intersensor interference (ISI) could greatly deteriorate the performance.

The system is designed using modular architecture and concurrent executionm ensuring smooth coordination between tracking and obstacle avoidance tasks. Line Tracking Module Functionality: a): Reads ...
