Description: This project integrates automation and security into a single unit. Also abnormal condition of any sensor is detected immediately and message is given as an alert to the user PC. Monitoring and controlling home environment in real time is made possible through LAN.
In This project we use a microcontroller(89S52) which controls the electronic devices through the relay driver(ULN2003). Also we are using PC, which is used for monitoring purpose. The temperature sensor(DS18S20) senses the temperature. Based on the temperature, the microcontroller produces the desired output. Thus our project helps us in constant touch with our home environment ensuring the safety of our home Platform: |

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.
