Getting the schematic is easy. Getting the housing parts and guts quantity one will not compete with $2 at the store.

Old solar garden lights used an LDR but they got sunburned after 2 years outside. New solar garden lights use the glass-covered solar panel to detect light and dark. Old solar panels with a plastic cover also got sunburned and failed after a couple of years.

I need to build the circuit for education purposes

I train a group of electrical technicians in the field of home electrical wiring.

I want to build the circuit because its components are available to me

I'm glad you're not my teacher.

Fine, buy one as pictured in post #4 ; dismantle it to pieces. Now you have ALL the parts to build one to train all your technicians explaining how to build one...

Line powered, or is there a separate DC source to power the circuit.

You don't say where you are located. Here is a British site with an assortment of kits:

Have you tried a web search for "photoresistor relay circuit"

Here is one of the ones that comes up right away when I do that

I just noticed you said Triac, just a second...

I also get a lot of results with "photoresistor triac circuit" I picked one that has specific component numbers. If some components are hard to get where you live, there are at least 50 results you could browse to find one that suits you.
