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 research team at Chalmers University of Technology, Sweden, has developed new laser technology that could lead to tiny, cost-effective biosensors. The sensors integrate lasers and optics together on ...

An optocoupler tester is a small device that helps verify whether an optocoupler is functioning properly or has failed. In labs and repair work, optocouplers often fail without clear signs. They may ...

The Army-led Joint Interagency Task Force 401 has released a new public guide explaining how counter-UAS detection technologies work and how they are designed t ...

Want crisp images? Cleaning your camera's sensor reduces smudges and particles from appearing on your images — here's how to do it.

To unlock materials of the future, including better photocatalysts or light-switchable superconductors, researchers need to ...

Both image photodetector arrays and retinas are pixelated sensors that dynamically extract various features from the visual scene—e.g., color, brightness, and contrast—before transmitting electrical ...

A team of researchers have developed an innovative image sensor that integrates liquid biological environments with organic electronics ...
