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….???1. Saves time2. Save money (Long run)3. Self Maintenance4. Security5. Makes life easy
INTRODUCTION
When you press a button in the telephone set keypad, a connection is made that generates a resultant signal of two tones at the same time. These two tones are taken from a row frequency and a column frequency. The resultant frequency signal is called "Dual Tone Multiple Frequency". These tones are identical and unique
What Is DTMF…?
We Will Use 89C51 Microcontroller.
It Is a 40 Pin Microcontroller.
Mostly Used DTMF Receiver IC Is The Motorola MT8870.
Used In Electronic Communications Circuits.
MT8870 is an 18-pin IC.
We Will Use 14 Pin LCD.
