Abstract: The growing need of energy efficiency and the sustainability of urban infrastructure has resulted in the use of smart technologies to automate the usage of public utilities. An example of ...

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 ...

Smartphone cameras are becoming smaller, yet photos are becoming sharper. Korean researchers have elevated the limits of next-generation smartphone cameras by developing a new image sensor technology ...

CU Boulder researchers have built high performing optical microresonators opening the door for new sensor technologies. At its simplest form, a microresonator is a tiny device that can trap light and ...

If you’ve ever stumbled through a dark kitchen at midnight or struggled to find something in a shadowy closet, the MCGOR 10-inch Under Cabinet Lighting 2-Pack is about to become your new best friend.

Blue light is a high-energy part of visible light from the sun, screens, and light-emitting diode (LED) bulbs. Your cornea and lens don’t block blue light the way they block ultraviolet (UV) rays.

CU Boulder researchers have engineered ultra-high-performance optical microresonators that trap and amplify light with remarkable efficiency, paving the way for powerful next-generation sensors.

The ESP32 creates a Wi-Fi hotspot (SoftAP). When a device connects and opens the ESP32 IP address in a browser, a web page displays live sensor readings collected from the connected sensors.
