Abstract:

This project discusses about developing a novel safety system to prevent accidents especially in high alert zones like Schools, Colleges and Hospitals using Received Signal Strength Indicator(RSSI). Power level is measured using RSSI by making use of a RF client device as receiving from an access point or router. Most wireless devices have capability of measuring received signal strength .There is router fixed at school which has open Wi-Fi that emits RF signals. The project devices consist of an Arduino UNO module, LCD, APR voice and speaker and a Wi-Fi module which is attached to the vehicle being driven. Whenever a vehicle is driven nearer to high alert zones, the speaker attached in the vehicle indicates an alert to the user to reduce the speed of the driving vehicle in case if it is driven beyond the set speed. If the user does not reduce the speed, the module attached to the vehicle automatically controls the speed to the set speed thereby ensuring the safety of the driver and the people around. The vehicle can then be normally driven at any speed after crossing the area. Thereby the precious lives can be saved by controlling the speed automatically.
