Place the IR light barrier strategically so it can warn you when someone is near!

This kit consists of two parts: an infrared transmitter and a receiver. As long as the receiver is able to detect the infrared beam that is sent out from the transmitter, nothing will happen. But once the signal is obstructed, an alarm will go off. For example, place both parts on either side of your bedroom door. The buzzer will sound the alarm when your parents or other unwanted intruders try to enter.

Many applications are possible: announce visitors, warn against burglars, set limits, conduct science projects... The generated beam carries up to 4 m away. When the beam is broken, the buzzer sounds an 85dB alarm and a LED indicator lights up. The receiver is powered by a standard 9 V battery (not included). The transmitter is equipped with a DC jack (9 V / 20 mA).

Attention: only suitable for indoor use.
