Earthquake Alarm System

Earthquake Alert System
The system is based on the ADXL335 accelerometer that has a detection range of ±3 g. It can measure the static acceleration due to gravity , as well as dynamic acceleration resulting from motion, shock, or vibration.
A metal ring mounted on the sensor ADXL335 contains perimeter loose steel spheres and magnifies the weak vibrations of the building creating a more intense shock to the sensor
the vibration of the building will turn on the device and it will sound alarm
the LED will turn red
will also activate wireless receivers alarms in other rooms at frequency 433Mhz

the appliance must be plugged in in standby mode in a room outlet the LED will be green (standby mode) Ability to enable / disable device with Power switch
the vibration of the building will turn on the device and it will sound alarm the LED will turn red
will also activate wireless receivers alarms in other rooms at frequency 433Mhz when the building stops vibrating the audible alarm will stop the LED will turn yellow and the device will return to standby mode
the LED will remain yellow (as a memory) reminding that there has been a vibration
if we want to restore the entire system to its original state we ,press the reset button
