In this video, I'm exploring the use of Mini PIR Sensors with ESP32 with both Arduino-based projects as well as making a movement sensor for Home Assistant by using ESPHome. The sensor is quite ...

A new laser range-finding technique, inspired by quantum physics, that can measure distances under strong solar background ...

In this video I'm building an Arduino Heart Rate Monitor that is housed in a toy handle in the style of the Star Trek Tricoder. The device uses the PulseSensor with an Arduino Pro Mini and an OLED ...

Current vision systems for robots and drones rely on 3D sensors that, although powerful, do not always keep up with the ...

Researchers at Pointcloud GmbH in Zürich, Switzerland, have packed advanced 4D sensing technology — ...

Combining a database with over 1.5 billion shots, GPS and an ultra-accurate laser, the Arccos Smart Laser goes far beyond distance and slope.

A quantum net for dark matter: A distributed intercity network of quantum sensors is placing additional constraints on the parameters that axionic dark matter could have. (Courtesy: USTC) A new of way ...

Abstract: Distributed acoustic sensors (DAS) based on coding technology can extend the sensing distance while ensuring high spatial resolution. However, due to the high sidelobe level of the aperiodic ...

Abstract: Energy-efficient image acquisition on the edge is crucial for enabling remote sensing applications where the sensor node has weak compute capabilities and must transmit data to a remote ...
