Homemade Laser Trip Sensor

Make a diy laser tripwire alarm for just a few bucks.

Homemade laser trip sensor.

It beeps 3 times and the data is sent to the serial port then returns to the armed mode. In the video above make magazine shows how to create your own laser tripwire for just a few dollars worth of electronics equipment. 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. But you can also connect the tripwire to a larger security system.

As part of a whole house security system you have more options in how the system alerts you. In this article you will learn how to build a laser trip wire out of inexpensive electronic components and you will build two circuits the laser beam sender circuit and the laser beam receiver circuit. 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. In trip mode the tripwire has been tripped.

No security system is complete without lasers. It checks if the value from the photo resistor dips due to the laser being broken when the laser beam is broken the trip mode is started. To connect your laser tripwire to another circuit connect the grounds of both circuits. Laser pens can still be dangerous and should never be directed toward anybody s eyes.

Insert your photoresistor into the breadboard. In this project we ll use a low powered laser pen instead. Laser beams that are visible in daylight or even in the dark are very powerful and can be extremely dangerous.

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. Here it is created by a single laser beam a small light sensor brick and a series of optional reflectors mirrors. With this you can cover an entire house.
