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 during disasters  FSO allows quick wireless communication by transmitting light beams through air  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
