Soldier Monitoring and Tracking System using ESP-NOW and SMTP Protocol

The paper introduces a Soldier Monitoring & Tracking System for real-time battlefield surveillance. Integrated with pulse sensors and GPS modules, soldiers' vital signs and locations are transmitted to a central base station via ESP32 microcontrollers. To address combat communication challenges, we utilize the ESP-NOW protocol for rapid message transmission within a 480-meter range. Additionally, soldiers can trigger distress signals, providing precise location and pulse rate information to nearby medical facilities. In emergency situations, SMTP protocol is used to send emails to hospitals. Through this integration of advanced technology, our system ensures efficient communication and enhances soldier safety in high-risk environments.
