A comprehensive IoT-based smart irrigation system with AI-powered predictions, real-time monitoring, and automated control. Built for production deployment with modern cloud infrastructure.

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 ...

In this video I'll be showing you how you can control the contrast and the back light brightness of a 1602 LCD display with just the Arduino. The contrast is typically adjusted with a variable ...

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 ...

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 ...

An optocoupler tester is a small device that helps verify whether an optocoupler is functioning properly or has failed. In ...

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.

Objective To synthesise the evidence regarding the risks and benefits of physical activity (PA), prescribed aerobic exercise treatment, rest, cognitive activity and sleep during the first 14 days ...

Sensor measurements typically translate physical phenomena of interest into electronic-circuit parameters such as resistance and capacitance, which can then be read with a bridge circuit. Bridge ...
