Homemade Laser Trip Sensor

So in this project i am going to show you how to build a laser tripwire alarm from a laser point a couple of mirrors and a few dollars of electrical parts.

In the video above make magazine shows how to create your own laser tripwire for just a few dollars worth of electronics equipment. Laser pens can still be dangerous and should never be directed toward anybody s eyes. With this you can cover an entire house.

No security system is complete without lasers. In trip mode the tripwire has been tripped. Here it is created by a single laser beam a small light sensor brick and a series of optional reflectors mirrors. This video incredibly short for it s massive content will teach you how to make a laser tripwire that combined with a photoresistor can trigger just about any device.

In this video i will teach you how to set up your own laser tripwire home security system. The laser trip wire build. Insert your photoresistor into the breadboard. You can make traps alarms awesome party decorations and all sorts of other awesome things with this easy to make device provided you have a soldering iron and a local electronics store to buy some parts.

As part of a whole house security system you have more options in how the system alerts you. But you can also connect the tripwire to a larger security system. It beeps 3 times and the data is sent to the serial port then returns to the armed mode. If also lets you confirm the alert with other sensors.

In this project we ll use a low powered laser pen instead. To connect your laser tripwire to another circuit connect the grounds of both circuits. Laser beams that are visible in daylight or even in the dark are very powerful and can be extremely dangerous.
