This document describes an IoT-based smart ambulance monitoring system with traffic light control. The system uses an Arduino UNO, GPS Neo 6M module, and SIM 300A GSM module to send the ambulance's real-time location via text message to the traffic control room and hospital. This allows the traffic control room to clear routes for the ambulance by controlling traffic lights on its path. The goal is to help ambulances reach the hospital faster in emergency situations to save more lives.
