Project: Light Fence (Security Alarm)

Posted on Saturday, February 16, 2013 by LEAD

Shruti V (SKVMCT)

Shruti devised a security alarm that can detect a moving person from several meters away by using electrical light beams and sensors.  After detecting the person, the device will produce a beeping sound to alert the homeowner.  Shruti’s device proved very helpful for everyone, but has been especially helpful for older people.
