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.
