In this paper, an alarm system for four types of emergency states (explosion, car accident, earthquake and fire) is developed. This system divided in to two parts: transmitted part (Arduino, sensors, GSM, GPS), and emergency part (center site, sub center sites). Center site is included (Android phone, Server), Sub center sites (helping centers) represented the mobile phones of competent authorities like police center or hospital. The alerting in this system as a SMS message is sent by GSM. The system used Haversine formula to determine the nearest sub center from emergency state that receives the SMS alarm message from transmitted part. Also the path is tracked using Google map application.
