TEMT6000 is available as a miniature transparent mold for surface mounting onto a printed circuit board. In addition to the TEMT6000 ambient light sensor, only one resistor is required to complete the ...

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 ...

Description This circuit shows how to use an ordinary LED as a light sensor. It makes use of the photovoltaic voltage developed across the LED when it is exposed to light. LEDs are cheaper than ...
