Recently an ad on YouTube about an acoustic light sensor/switch module piqued my interest. Out of curiosity, I contacted the online vendor and bought a pair. Named MR-SK50A, the module is less popular ...

By capturing sound data and processing it through Audacity, this system provides a comprehensive tool for analyzing acoustic signals. The project showcases practical applications in sound detection ...

Acoustic emission sensors are devices that capture the sound waves generated by the sudden release of energy within a material. This release of energy can be caused by various phenomena, such as ...

Unseen threats can have serious consequences. In homes, schools or hospitals, small drones can slip past cameras or radar and invade privacy ...

A model of a utopian traffic system was designed using Arduino as the microcontroller, LDR, LM393 sound detection sensor module and HW-201 1R sensor. Sensors used: HW-201 infrared (IR) sensor, Light ...

Acoem ATD technology detects both the muzzle blast and the ballistic sound wave of a bullet in motion, allowing detection and location from a single sensor. At ISC-West, booth #7041, Acoem, a ...

This work presents a novel marine acoustic sensor based on a differential dual-channel triboelectric nanogenerator (TENG) design for underwater low-frequency sound wave detection. By constructing a ...
