Top Cat Phase II

P12352

Engineering Specs:•Detection Range of 25’•Safe Deterrent•0.8”x1”x0.5” Enclosure•Does not restrict cat’s movement (Light weight)

Team Members:Mahdi Massey – EEBrian Rosenberger – EEAndrew Strobel – EETsz Hang Yung - EE

Mission Statement:Goal of this project is to develop two short range alert devices that will fit on two collars to prevent cats from fighting

Faculty Guide:George SlackSponsor:David Perlman

Blue Trace is the IR Receiver, when the receiver goes low, the 555 timer outputs a 25kHz signal to the output speaker (Yellow Trace)

Both collars are transmitting a burst of a 33kHz IR signal and looking for a 33kHz signal. When this signal is detected, this triggers the 555 timer to output a 25kHz audio pulse. To prevent the collars from detecting it’s own signal, an inverter was used to turn off the detector when the circuit was transmitting.

Test Results:•Detection range of 40’ indoors and 11’ outdoors•Deterrent is a 25kHz high frequency sound•Size is 2.5”x1.5”x1.0”•Battery life of greater than 12 hours on standby

Technologies:•IR for collar detection•RF signal to alert the owner•High Frequency sound for deterrent
