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 ...

Even though the technology has been in use for decades, IR blasters are a key part of today's smart TVs and will be for years to come. Here's why.

After decades of intense research, surprises in the realm of semiconductors—materials used in microchips to control ...

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 ...

Today I learned that WiFi and Bluetooth LE could NOT be used simultaneously on Arduino boards featuring the ESP32-based u-blox NINA-W102 wireless module, ...

Inspired by the infrared sensory organs of snakes, which allow them to detect prey in complete darkness, researchers at UNIST ...

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 ...

Whether you're searing steaks in a cast-iron skillet, calibrating a pizza oven, or checking the temperature on HVAC equipment, a reliable infrared thermometer is a necessity not only for accuracy but ...

General Atomics Aeronautical Systems, Inc. (GA-ASI) and the U.S. Air Force held another autonomy flight exercise yielding new and important developments in the operation of Collaborative Combat ...
