Abstract :

Industrial Settings Need Robust Security Against Theft And Illegal Access Since They Contain Priceless Machinery, Private Information, And Ongoing Manufacturing Processes. Conventional Security Techniques Including Camera-based Surveillance Systems, Single-sensor Alarms, And Human Monitoring Frequently Have High Computing Demands, Many False Alarms, Slow Reaction Times, And Reliance On Steady Internet Access. A Multimodal Anti-theft Alarm System Is Suggested As A Solution To These Problems. To Increase Detection Reliability, The System Combines Three Sensing Techniques. A Laser-LDR Pair Monitors Beam Disruption To Detect Unwanted Entry, And An Infrared Sensor Detects Motion Within The Secured Area. A Force Sensor Also Senses Pressure Or Physical Contact With Surfaces Or Equipment That Is Restricted. The System Increases Intrusion Detection Accuracy And Decreases False Alarms By Integrating Many Sensor Methods. As The Central Processing Unit, An ESP32 Microcontroller Continuously Gathers Sensor Data And Manages System Activities In Real Time. Real-time Status Updates Are Provided By An I2C LCD Display, And When Suspicious Behavior Is Identified, A Buzzer Immediately Sounds A Warning. Authorized Users Receive Immediate Notifications From A GSM Module For Remote Monitoring. In Order To Guarantee Continuous Functioning In The Event Of A Power Outage, The System Additionally Incorporates A Controlled Power Supply With Battery Backup. Improved Detection Accuracy And Quicker Reaction Times Are Shown By Experimental Results.
