These DTMF codes can be decoded and utilised for useful purposes. The circuit utilizes IC8870 for DTMF decoding. Microcontroller 89C51 reads these codes and takes necessary action. Door latch can be opened by entering the correct password; we can also connect security sensors of our choice. In case of any breach of security, the device will dial out the pre-stored number and deliver an emergen ....etc [:=Read Full Message Here=:]
