DISASTER MANAGEMENT SYSTEM USING FREE SPACE OPTICAL COMMUNICATION Introduction India prone to natural disasters like floods, cyclones, earthquakes etc. Disaster management deals with protecting people and property duringdisasters FSO allows quick wireless communication by transmitting light beams throughair Allows high bandwidth data transmission without need for license Proposed System Detect disasters like earthquakes, floods using sensors Interface sensors to microcontroller to monitor readings Trigger audio messages on crossing threshold values Transmit audio messages to remote locations using laser Intensity modulation of laser beam with audio signal At receiver, convert light to electrical signal and play audio Methodology Use microphone for audio input, record messages in voice module Interface sensors and voice module to microcontroller Amplify messages and use laser driver to modulate light signal At receiver, solar panel converts modulated light to electrical signal Amplify recovered signal and feed it to speaker Results Implemented voice recording and playback circuitry Interfaced sensors and voice module to microcontroller Built transmitter to intensity modulate laser with audio Constructed receiver with solar panel for opto-electrical conversion Conclusion Prototype demonstrates FSO based disaster alert system Quickly establishes communication without infrastructure
Can transmit emergency data to aid disaster response Leverages high bandwidth of FSO for critical applications Key Highlights FSO allows rapidly setting up wireless communication during disasters Sensors interfaced to microcontroller detect calamities like quakes, floods Recorded audio messages transmitted by modulating laser beam Solar panel at receiver converts light signal back to electrical signal Demonstrates using FSO for disaster alert and emergency communication
