Infrared Light Barrier Module

Infrared Light Barrier Module With this module it is possible to set up an infrared light barrier with a maximum distance between the transmitter & receiver of a huge 30 metres (nearly 100 feet)! Breaking the beam throws a relay (24V 3A, 250V 1A) which could be used to switch an appliance such as lights, alarms, etc. The transmitter requires a 9V 50mA power supply & the receiver requires a 12V 100mA power supply.
