Hi everyone,

Firstly i must say that it is my pleasure to be here.It is certain that this is a helpful society.I must design "An analog circuit that acts as a light sensor and controls a relay that activates a street lamp".But my electronic knowledge consists of only about "theory".Which i learn from the lessons.This is my first designing project.I would be pleased if you help me here.Thanks

Google on "LDR' or "CdS C cell". A light dependent resistor plus a couple of fixed resistors and a transistor will make that analog circuit. Every automatic night light uses a CdS cell, including street lamps.

Whoops, that "CdS C Cell" comes from a wetware malfunction. Should be "CdS cell".
