Description: Introduction
Dial your number using DTMF phone or Cell phone from anywhere in the world and remotely turn on/off any of the 8 relays. The MCU on the interface senses Telephone ring, Automatic telephone pick up, and line hang up, displays information on a 16x2 LCD module and controls the relay switching. This interface uses the popular MT8870 DTMF decoder IC along with AT89S51 Microcontroller.
Features
• Outputs - Relays x 8
• Fully microcontroller based interface using AT89S51.
• Auto line pick up.
• On Board flash EEPROM that stores system Parameters and password and relay status (no require battery back up)
• User settable password for security.
• 16x2 Line LCD module to display Status and Error Message.
• Acknowledgement tone out put for the user.
