Wireless alarm system using AVR microcontroller

摘要

The main aim is to design a wireless alarm system using AVR microcontroller.This alarm system had a force sensor as its main component. The force sensor senses the force or pressure and then it create a sound which can make a person to avoid problems. This alarmsystem is used for the home security to detect presence of intruders getting into the home. A servo motor is also installed here this shows the automatic movement of motor which is implemented for automatic control of the gate. So, we are designing a wireless alarm system which also acts as an alarm system and also for automatic barrier control. This doesn’t occur at a time a certain time has been kept by using time delay.
