This idea describes an MCU interface for a 1-Wire temperature sensor interface that offers high accuracy while using less board space. The circuit can be modified for use with any 1-Wire device. The ...

Ambient light is increasingly being used as a source of energy. To help designers of such systems, this circuit accurately measures ambient light intensity over four decades of measurement. The design ...

This circuit uses a thin piezoelectric sensor to sense the vibrations generated by knocking on a surface; eg, a door or table. Basically, it amplifies and processes the signal from the sensor and ...

Here we describe an electronic system that uses a dedicated water-level sensor to switch off the pump motor as soon as the ...

MIT chemists have devised a new way to wirelessly detect hazardous gases and environmental pollutants, using a simple sensor that can be read by a smartphone. With inexpensive sensors, the researchers ...

Controlling sensori-motor systems in higher animals or complex robots is a challenging combinatorial problem, because many sensory signals need to be simultaneously coordinated into a broad ...

Capacitive touch sensors are based on the electrical capacitance of the human body. When, for example, a finger comes close to the sensor, it creates a capacitance to Earth with a value of 30 to 100 ...

Self-driving cars typically use radar or LiDAR technology to avoid collisions with other vehicles. Scientists have now created a much simpler insect-inspired system that could serve the same purpose ...

CNET’s expert staff reviews and rates dozens of new products and services each month, building on more than a quarter century of expertise. Editors' note, Dec 14: You can find all of our coverage ...

The act of turning on your PC is a simple one, but pressing the power button isn't the only way to do it. In fact, I would argue the power button is archaic, and there are significantly more ...
