hi ppl,
i m a new member. m a first year college student (eletronics) and this is my first project.
"BURGLAR ALARM USING PHOTOELECTRIC EFFECT".
i have to present a working model and a project report on this thing. can someone plz guide me through this. i need the circuit diagram, components needed in a circuit, how to assemble them, wat shud my project report contain....etc,etc.
plz reply soon. Thank you in advance.
guys i really need help...bye
Nobody here will do your homework for you. However, if you present your thoughts and ideas with maybe a few rough circuits people will help you. You have to be the one to take the inititative and put out some effort.
You need to think this through. Clearly a photo-cell will be used to detect an intruder. Will it detect visible or infra-red radiation? Do you want the cell to detect infra-red radiation from the intruder, or to detect interruption of a beam by the intruder? What sort of alarm signal do you want? How long will the alarm signal last? How will you reset the alarm? Is a local or remote alarm indication needed? What will the circuit be powered by? .......
When you have a clearer idea of your requirements then is the time to ask for help if you need it. We're not going to do all your work for you .

Before the foundation was laid I added another 3.5m of soil well above the max flood line in the village.
The Khlong nearby (passing directly along one side of the garden) even flooded the bridge leading to our ground, keeping the flood well 1.5m below the foundation.
Water masses move south quickly having flooded Ayuttaya (the king's residence) and Bangkok.
Two years ago we had a dam broken near our house with no water reaching the top of the soil.
