Product Description
Just Break The Beam! Use the power and invisibility of an IR light beam to your advantage! This little kit includes the transmitter and receiver for a highly efficient intruder alarm. Includes an Infra-red transmitter board that generates a high power and focused invisible beam of light that covers up to 13 feet! The matching receiver features a high sensitivity IR receiver that picks up that beam and when broken, sounds a built-in 85dB audible alarm and lights an LED. Both the transmitter and receiver operate on standard 9VDC batteries to prevent problems during power failures. Perfect to announce visitors, burglar alarms, set boundaries for animals, and for science fair projects. Transmitter measures 2.2 x 1.6 and the receiver measures 3.9 x 2. From Velleman. ;
