Door
Minder Infrared Beam Sensor Kit
This
kit uses an infrared beam to monitor door & passage-ways or any other area.
When the beam is broken a relay is tripped which can be used to sound a bell or
alarm. Suitable for detecting customers entering a shop, cars coming up a
driveway, etc. The IR beam is very strong. Distances over 25 yards can be
monitored with this Kit. A 12VDC supply is required to power the kit. A 12V wall
adaptor is fine. Provision have been made so that only one power supply needs to
be used to power both units. The relays in this kit are rated to switch mains
voltages.
