WIRELESS LORA COMMUNICATION BASED SOLDIER SECURITY ALERT SYSTEM
By utilizing IoT and advanced wireless communication technologies, the "LoRa-Based Soldier Security System Integrated with IoT" seeks to improve troops' safety and real-time surveillance while they are in the field. The two main components of the system are the transmitter (Tx) and the receiver (Rx). An LCD display, a buzzer, a LoRa transmitter module, a keypad emergency button, and essential sensors like SpO2 and cardiac sensors are all integrated into the Tx unit. The Rx unit has an LCD display, a buzzer, a LoRa receiver module, and Internet of Things integration for remote monitoring. On the Tx side, data from the sensors is continuously tracked, including vital health indicators. Both the Tx and Rx devices send out a warning through buzzers and LCD screens if any of the parameters exceed predetermined threshold levels or if the emergency button is touched. The alarm is sent to an Internet of Things server at the same time so that higher authorities are notified in real time. An ESP32 is used on the Rx side of the system for Internet of Things connectivity, while an ESP32 is used on the Tx side for sensor data collection. This project provides a long-range, dependable, low-power communication solution that will improve overall military safety and operational efficiency while guaranteeing prompt replies in emergency scenarios.
