Door Minder Electronic Kit
This kit uses an infrared beam to monitor doors, passage-ways or any other areas of interest. When the beam is broken a relay is tripped which can be used to sound a bell or alarm. This switch is suitable for detecting customers entering a shop, cars coming up a driveway, etc. The IR beam is very strong allowing distances up to 25 yards to be monitored. A 12VDC supply such as AC Power Adapter 12 VDC must be provided. One power supply can be used to power both units. The relays in this kit are rated to switch mains voltages.
