Hello everyone, i found this forum and seems like lots of knowledgeable people here.
I would like to build a laser beam “fence” in the back yard that would have the laser beams visible at night, but also when someone crosses the laser beam, it would set off an alarm or a lightbulb.
Kind of like the cheap driveway motion detection alarms but it would have a visible laser beam from the laser diode to the sensor that would receive the laser beam on the other end of the line.
The distance for each side of the “fence” line wound be about 40 feet. I would like to make it a V pattern, 2 laser beams each coming from each corner of the house wall to a receiver/sensor at the far end of the back yard/patio. It would be two beams one at waist height and another at knee level.
The purpose is mostly for entertainment/artistic purposes for my guests when they come visit, but at the same time act as a motion detection system.
From my research on here, I understand that I would need a 520-532nm spectrum laser to be best seen by human eye and needs to be at night. Are there any units or diodes that can be hardwired to AC power and be turned on continuously instead of the battery operated clicker ones which would have a heat sink or anything else to help it not overheat? Or maybe I can stagger two in the same direction and have them turn on and off taking turns every 10 minutes or so?
Also are there any receivers or sensors (not sure what to call them) like what I describe above that would receive the laser beam and then trigger an alarm or electrical impulse when the laser beam is interrupted?
Would appreciate your suggestions! Thank you!
