Emergency Communication Device

In disaster-prone areas, communication infrastructure often fails, leaving affected individuals unable to reach emergency services. This project presents an Emergency Communication Device that operates independently of cellular networks, using Arduino Nano, NRF24L01 modules, and a NEO-6M GPS module to transmit location and voice messages wirelessly. The device integrates a MAX4466 microphone amplifier for audio input, a PAM8403 amplifier for audio output, LED indicator lights, and a solar-powered lithium-ion battery for continuous operation in remote areas. Additionally, the device is waterproof and includes a built-in light source for visibility in low-light conditions.
