Kitronik Light Activated Switch
KI 2112
This light-activated kit is also available as a temperature-activated project kit. The output of this board can be used to control other electronic circuits, turning them on automatically when it goes light or dark.
The board has space for an LED with a 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.
Features:This Light Switch Kit detects the brightness of its surroundings using a Phototransistor. The kit acts as an automated on/off switch (light dependable) for many devices.
Contents:1 x 1MΩ Potentiometer. 2 x BC337 NPN Transistors. 1 x Phototransistor. 1 x 220Ω Resistor. 1 x Light Activated Switch PCB
Possible applications include:Garden light that switches on automatically at night. Drawer alarm, which sounds when a dark drawer is opened. Line following robot (using 2 light-activated boards).
