hi everyone
i'm new to this forum.....
The aim of the project is to build a low-cost, invisible laser circuit to protect our house from thieves or trespassers. A laser pointer torch, which is easily available in the market, can be used to operate this device. A laser torch powered by 3V power supply is used for generating a laser beam. A combination of plain mirrors is used to direct the laser beam around the house to form a net. The laser beam is directed to finally fall on an LDR that forms part of the receiver unit. Any interruption of the beam by a thief/trespasser will result into energisation of the alarm
i like to add on.....i.e call the owner.....when an intruder cuts the laser beam.....i checked for many ways to connect a call.... finally read an article...that uses just relay to activate a call.....will that logic works???....please help me with your suggestions
