This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot ...

UV (ultraviolet) sensors of all sorts have been an interest of mine. They become interesting when you find the diversity of real-world practical applications. While searching for affordable UV light ...

Sometimes, projects start in somewhat unlikely places. This one began when [Istvan Raduly] scored a fake raven at a neighbor’s garage sale and decided to turn it into a thunder-and-lightning ...

Parking sensors have become a must-have these days given the crowded cities we live in, but instead of paying hundreds of dollars to get them installed in your car, why not build your own at home?

Arduino has announced the official release of Arduino IoT Cloud, an “Internet of Things Application Platform” enabling you to easily develop and manage IoT apps. The system first emerged back in ...

An overwhelming majority of handheld devices these days have ambient light sensors built into them. A large percentage of TVs and monitors do, too, and that proportion is growing. The sensors allow ...

Visible and shortwave-infrared hyperspectral imaging previously demanded costly multichip or multi-camera solutions with lower SWIR resolutions. Sony researchers addressed this challenge with a copper ...
