I'm making an alarm system based on infrared rays

[From: ] [author: ] [Date: 12-04-05] [Hit: ]
-That is a very odd bag of bits that you have listed there.There is no way that anyone can really help without seeing the circuit diagram of the whole thing.Did you get the circuit off the internet or from somewhere else?If you can post a link to the circuit in additional details, we may be able to help.-You dont have a sensor in that list.......
using diode 1N4OO1, 68 ohm resistance, 2 ir emitting diodes and 9 v supply. are he specifications right or i should change the voltage and resistance..because the sensor is always producing sound and not sensing the ir rays..please reply soon. its extreme urgent.

There is no way that anyone can really help without seeing the circuit diagram of the whole thing. Did you get the circuit off the internet or from somewhere else?

If you can post a link to the circuit in 'additional details', we may be able to help.

You don't have a sensor in that list. In fact, I don't see how you can make an alarm out of those parts.

PS, it's 1N4001, which is a power rectifier.

A schematic would be helpful.

"..because the sensor is always producing sound and not sensing the ir rays.."

What are you using as an IR detector? Nothing in the list of parts makes sound.
