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 ...

Beneath the South China Sea, China is building a vast acoustic surveillance network designed to detect the world’s quietest ...

In an advance in microsensor technology, researchers have unveiled an ultra-sensitive gas detection method using surface acoustic wave (SAW) sensors enhanced by the physics of exceptional points ...

They're trying out gunshot detection systems, devices that use a network of acoustic sensors installed in high-crime areas. When the sensor is triggered, an algorithm confirms that it is gunfire, ...

Inside the PAS sensor there is an infra-red light source and a microphone. “Because there is no longer a need to place a detector opposite the IR emitter, external impacts will not have an effect.” ...
