The first thing to add was a power management circuit, and after one iteration he settled on a circuit which can provide the board power from a battery or a USB cable, while also managing the ...

This Circuit can compare the Light level in an area. It uses a PN Photodiode as the light sensor and IC CA3140 as voltage comparator. The circuit is ideal as the front end of burglar alarm circuits.

OxyLED has a number of options to keep things sufficiently lit. Today we’re looking at the OxyLED USB rechargeable motion sensor light.

The relatively high yield of complex operational circuits proved the potential of the technology, with improvements readily achievable by optimizing nanowire synthesis and fabrication of the devices.

Scientists at Lawrence Berkeley National Laboratory and the University of California at Berkeley have created the world's first all-integrated sensor circuit based on nanowire arrays, combining ...

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 ...

In addition, the company has an outlet cover with integrated LED lights and light sensor, so you don’t have to use an outlet for a nightlight.

Toyota Motor said it will recall 1 million vehicles in the US because a short circuit in a sensor could cause air bags not to deploy as designed.

This light sensor switch circuit allows the automatic connection of a lamp when the light is low (at nightfall) and will maintain the lamp ON for a certain period of time. This time can be adjusted ...
