What is HACS?

• Home Appliance Control System accessed by a remote device such as mobile phone or a palm-top to allow a home owner to control, monitor and coordinate home appliances.

Why HACS ???

When: you are in a traffic jam on the highwayWhat: You set microwave oven in a slow cooking mode

Slow cooking mode

1. Saves time2. Save money (Long run)3. Self Maintenance4. Security5. Makes life easy

What’s inside black box• Black box consists of DTMF

decoder and relay circuits for integrating it with household circuits

• Technology used in interactive voice response system (IVRS) i.e. the customer care centre.

• DTMF stands for dual tone multiple frequency

• Every key of telephone is associated with a tone comprising of frequencies from two groups viz. low freq. and high freq. group.

• DTMF_Decoder.wav

What we have done• Designed DTMF

decoder circuit which consist of three parts:-

i. DTMF to BCD decoder

ii. BCD to 1 of 12 decoder

iii. Relay circuit controlling

• We have implemented this for controlling

i. Controlling four motions of robot

ii. And controlling household devices

• IC-CM8870• IC-74LS138• IC-CD4013• IC-7805(Regulator)• RELAYS• TRANSISTOR-BC547• LEDS• CRYSTAL-35795MHZ• TRANSFORMER• DIODE(1N4007)• RESISTANCE• CAPACITOR• POWER SUPPLY

• This is the front end user interface for decoding the DTMF signals.

• When any DTMF audio file is sourced to it then…

• GUI showing the decoded DTMF signals

• For key pressed with more than 1sec delay are considered new world

• Lighting and Appliance control

• Security systems & Access control

• Entertainment Systems

• Communication systems

• Wireless radio control

• Mobile wireless robot control

• Reporting during car accidents

• Almost Anything Else you can think of

Future planning cont.

• In coming days we will be completing the full software

• With dedicated IVRS response and fully automatic real time DTMF decoding.

• And your PC will be connected to your appliances as peripherals.

• And we can control our house by interacting with audio stored in PC
