AIM:
Design and Development of Wireless home security using Zigbee and GSM.
PURPOSE:
Theft rate increased day by day. Manual monitoring through security guards is expensive and will not possible by everyone. Here embedded products are come into picture and not expensive. Embedded products consist of controller and sensor interfaces which consume less power. Here we propose solution like wireless home security using Zigbee and GSM.
DESCRIPTION:
This project includes Zigbee module (HC12), which is connected to Arduino through UART interface. GSM (SIM800C) connected to Arduino UART. LM35 connected to Arduino analog pin. IR sensors connected to Arduino digital pins. DC fan controlled through relay which is connected to Arduino digital pin.
WORKING:
In this project we can monitor home through mobile phone and through Zigbee. Monitoring Zigbee placed at central room (central monitoring room). Sensors side section placed living room. LM35 reads temperature of room and if temperature more than45 degrees then fan will be ON also SMS will be sending. When fire occur then buzzer will be ON and SMS will be sending. Two IR sensors placed at door and window to detect intruder entry. If any intruder entry then SMS will be sending and buzzer will be ON. All these sensors data displayed on LCD and transmitting to central monitoring system.
