A simple and inexpensive circuit, suitable for many applications like the automatic switching of the lights in a shop window or a room according to the ambient light level.
 
The circuit uses a light dependent resistor (LDR). A light/dark option has been incorporated. The term 'light/dark' is used because the circuit has a PCB-mounted switch on board. In one switch position a light-to-dark transition will activate the relay.
 
In the other position a dark-to-light transition is required. So you can use the falling light on the detector to switch on a normally off circuit or switch off a normally on circuit.
 
Power supply: 12 to 15Vdc
Relay Contact Rating: 5A / 240Vac
PCB Dimensions: 60 x 32mm

 


Note: This is a soldering kit.
The electronic soldering kit consists of an
instruction pamphlet, a PCB (printed
circuit board) and all the electronic
components that are required to assemble
the complete circuit board of the kit. The
instruction pamphlet contains information
for assembling and using the kit.
The aim with the kit is for the end user to
do all the assembly work by soldering
(mounting) the electronic components
onto the PCB. It can be fun!
