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 ...

(Nanowerk News) Scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley have created the world's first all-integrated sensor ...

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 ...

Intersil’s ISL29015 light sensor/proximity sensor uses up to five times less board space and six times less current. The device comes in a tiny, clear 2mm x 2.1mm package and consumes only 50 ...

W. W. Biggs, A. R. Edison, Jerry D. Eastin, K. W. Brown, J. W. Maranville and M. D. Clegg An improved light sensor with a spectral response based on photon absorption between 400 and 700 nm was ...

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 ...

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.

Scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley have created the world's first all-integrated sensor circuit based on ...

Randomly oriented nanowires, on the growth substrate at left, are having a “bad hair day.” But after contact printing, the nanowires on the receiver substrate are highly aligned. Scientists at the U.S ...
