Notwithstanding the fact that these devices have been available for some time, they are still poorly understood by the general public. Laser trip wire alarms are becoming increasingly popular since they can detect intruders without the use of physical barriers. From our experience, the wireless technology is not reliable enough to be used in Escape Room puzzles. The warning could be anything from a loud siren to a hushed signal sent to a central monitoring station. Some are present outside of missions, and can have unique functions such as triggering the release of gas.

This project is based on the module, LASER module, a Buzzer, and a push button, the idea is very simple, the LASER is constantly projecting light to the module sensor, when a person or something passes through the light beam, the sensor will not detect the light anymore (When the light stops, the LDR will increase resistance, which means less current will pass, and we’ll get a voltage drop).This allows Jensen to slip through just behind a patrolling guard, or use unconscious or dead guards to disable the lasers indefinitely from any angle. It has a selector switch on the side that allows the user to set what key sequence will be “typed” once the system has been tripped. Destroying a laser emitter will trigger it, but temporarily disabling one with the stun gun won't, allowing safe passage. It was quite lowtech: A small switch with really thin wires at the bottom of the door, an enclosure with some transistors, resistors, a capacitor an optocoppler hidden behind the fourniture and a special mouse with wires attached to the left key. You can use many sensors of the same kind, or make each of them of a different kind – it all depends on your puzzle idea.

What is behind this little laser trip wire is actually a red laser line that triggers a latch-switch when tripped. As much as I hate The Internet of Things, a remote hosted version of this that could be set up to work remotely over wifi connection, without being hooked to a computer, but could trigger a webcam and microphone then I could access from my smartphone half the world away would be very useful. The Circuit Is Mounted Safely Inside An ABS Project Box That We Cut Out The Aperture For The Laser To Suit. A laser trip wire alarm could be just what you need to keep your possessions safe and secure, whether you’re seeking to secure your home or your business.They may be employed in scientific studies, such as determining the migration of microscopic particles or monitoring animals. My laser pointer (and all of the others I have seen) have a completed circuit when the end cap is on, so I connected the other alligator clip to the bit of metal on the inside of the laser pointer.

However, these limitations can be overcome by putting numerous laser trip wire alarms in an interconnected system or integrating them with other security technologies. The receiver circuit includes an electromagnetic relay to assist the switching process of external electric loads such as floodlights, home alarm systems, etc. We also import the sleep function from time; we’ll need this to slow the script down a little to give the capacitor time to charge.
