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. Manufacturer: KITSRUS.

The output pins are normally high and go low for xms when the corresponding button is pressed. the pin corresponding to that button goes low. You can use this circuit to control up to 14 relays or to control the movement of a robot. This circuit is intended to be used as a component of larger systems, so no PCB is supplied. It is up to you to breadboard the application then make your own PCB. A sample application/test circuit is provided. This kit includes: A 14 button Infra Red Remote Control. This is a pre-built remote which requires 2 AAA batteries (not included). a 3-pin Infrared Receiver Module, the Waitrony PIC1018SCL, which converts the modulated 38kHz signal into data pulses. An Atmel 89C2051-24PC microcontroller which we have preprogrammed to decode the IR data pulses from the remote control into one of 14 active low outputs. All required components for the microcontroller are supplied - a 12MHz ceramic resonator for the oscillator, resistor, capacitor and diode for the power-on reset circuit plus two 10K pullup resistors.
