Homemade Laser Trip Sensor

In the video above make magazine shows how to create your own laser tripwire for just a few dollars worth of electronics equipment.

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. Make a diy laser tripwire alarm for just a few bucks. If also lets you confirm the alert with other sensors. 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.

Laser beams that are visible in daylight or even in the dark are very powerful and can be extremely dangerous. In this project we ll use a low powered laser pen instead. Laser pens can still be dangerous and should never be directed toward anybody s eyes. As part of a whole house security system you have more options in how the system alerts you.

To connect your laser tripwire to another circuit connect the grounds of both circuits. No security system is complete without lasers. Insert your photoresistor into the breadboard. It beeps 3 times and the data is sent to the serial port then returns to the armed mode.

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. In this video i will teach you how to set up your own laser tripwire home security system. Onvian door sensor alarm anti theft burglar alert 120 db wireless window alarm burglar anti theft alarm for home shop security protection 4 7 out of 5 stars 20 9 99 9. 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.

But you can also connect the tripwire to a larger security system. With this you can cover an entire house. In trip mode the tripwire has been tripped.
