Kit Interruptor Ativado por Luz

Kit Interruptor Ativado por Luz

Informação do fabricante:

The Light Switch Kit detects the brightness of its surroundings using an LDR. The kit acts as an automated on/off switch (light dependable) for many devices.

The board has space for an LED with current limit resistor (both available separately) which will light when the output turns on.

The Darlington pair transistor configuration allows an output current of up to half an amp to be controlled. Operating voltage 3V to 12V (lower voltages allow for better adjustment of the switching point).

Note: This kit requires soldering.
