Color sensing (as well as detecting empty spaces) settled on IR-based sensors commonly used in line-following robots. You can watch the clock in action in the video embedded below just under the ...

An IR sensor is located near the TV and wired to the receiver, which can be many feet away in the equipment rack. The receiver has an amplifier and an "IR blaster" that showers IR signals to all ...

An Arduino replaced the OEM controller, and wired up to temperature sensors and an IR sensor that watches for ice buildup on the lower part of the coil, the heat pump is now much better behaved.

Powered by an Arduino Uno, this laser tripwire alarm project works much like those in movies. There's a tripwire — made up of a laser directed at a light sensor — that's placed somewhere the intruder ...

There are several types of pressure sensor devices. Sensors-- Pressure sensors convert a measured pressure into an electrical output signal. They are typically simple devices that do not include a ...

Many laptops are fitted with a three-axis shock sensor which detects sudden movements, including free falls and sudden impacts. When the sensor detects vibration or shock which exceeds a predetermined ...

Sensors are devices that detect and quantify physical aspects of the world around us. The measurement can either be read directly or converted to a signal for processing by electrical, hydraulic ...
