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 ...

The Arduino is a great way for hobbyists and pros alike to experiment with programmable objects, but it can be confusing for beginners without these tools.

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 ...

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 ...

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

Meshy integrates its Image-to-3D tool into Bambu Lab's MakerWorld MakerLab, while also launching Multi-Color Printing on meshy.ai -- together delivering the most seamless AI-to-print workflow on the ...

A team led by La Trobe University has drawn inspiration from nature to develop a breakthrough sensor that can rapidly track ...

The inventor behind the sensor used in most modern imaging devices has received a major award ...

The designers at Lightspark write: Humans can’t reliably recall colors. This is a simple game to see how good (or bad) you are at it. Dialed shows you a color for 5 seconds, then asks you to recreate ...

Light aircraft often use a heading indicator as a way to know where they’re going. Retired instrumentation engineer [Don Welch] recreated a heading indicator of his own, using cheap ...
