摘要：A smoke detector or smoke alarm is a device that detects smoke and issues a alarm to alert nearby people that there is a potential fire. They can detect fire in their early stages and give you those precious minutes to enable you and your family to leave your house in safety. Wireless communication enables transfer of data or signals over part of the entire communication network. Wireless implementation of sensor network ensures safety in terms of saving lives and property. In this paper wireless sensor network is realized using ARM 7 based microcontroller. The LPC2148 is a very popular ARM7 microcontroller with 512 KB flash, 64 KB of RAM and with several I/O peripherals. When potential fire is detected, the smoke sensor sounds an alarm .It also transmits a signal wirelessly to other sensors in the network. The microcontroller form the main unit of the system .It receives input from the sensors and wirelessly sends information to other sensors in the network to sound an alarm thereby preventing any disaster from occurring. GNU ARM/Keil compiler will be used for building the applications. LPC2148 development board will be used to test the built application. Additional sensors and wireless nodes will be used to demonstrate the complete setup.
