DTMF refers to dual-tone multifrequency signaling. This DTMF is used for telecommunication signaling over analog telephone lines in the voice frequency band between telephone telephones and other communication devices and the switching center. There are two types of communication we usually use - one is wired and another is wireless. In wireless communication that transmits the signal wirelessly, such as the use of radio frequency (RF) and in cable communication in which cables such as copper wire are used. In this project "Home Automation System based on DTMF" we will control our appliances wirelessly. Another important feature of this project is that we will not use any microcontrollers in it.
