This year’s project is an addition to last year’s Remote Controlled Home Project Last year’s project was programming a VCR through a remote PC This year’s project is to remotely operate and check the status of a deadbolt using a cell phone This will include adding feedback and sensors to check that status of household items and a cell phone to PC interface

Inherited from last year’s group Is composed of an IC8001 Chip, PIC16F877 and Altera EPM7032 Contains a Library of IR Codes Sends IR codes Connects to a remotely accessed computer and will be used to send and receive IR codes from the deadbolt

SIRCU Via Phoneline Deadbolt Status Infrared Signals Cell Phone IR Sensor/ Electric Door Stop PC Station

Cell Phone Interface: telnet or voice prompt Home PC: Software GUI implemented in Java, RS-232 SIRCU connection Wireless: 40 kHz modulated Infrared signals IR Sensor : IR receiver connected to PIC Electric Doorstop: power 16VAC (250mA) Deadbolt Status Unit: combinational logic and an IR diode to send status

The SIRCU will be modified for receive operations Construct a deadbolt status unit to relay an IR signal if the deadbolt is locked Construct an IR receiver to unlock/lock the electric deadbolt Achieve proper IR communication between the deadbolt sensor and SIRCU device Operate and check the status of the deadbolt via PC to remote PC

SIRCU has been tested, debugged and is now working correctly All system components have been ordered NEXT STEPS: Develop deadbolt status sensor Test IR communication between the SIRCU and deadbolt sensor
