Gsm Based Security System in Museums

Improved technology is being used by researchers worldwide to discover a remedy for robbery and trespassing. The design and implementation of a laser-based smart security system for identifying such activity is the subject of our paper. With the use of passive infrared (PIR) and laser sensors, it seeks to safeguard residences and museums against harm, danger, and criminal activities. Two sensors, such as a PIR and LDR sensor, an Arduino Uno microcontroller, and a GSM (Global System for Mobile Communication) module make up this security system. The technology is designed such that the circuit detects the cut-off and stumbles the alarm when someone interrupts the laser beam or PIR sensor. When someone examines it and manually turns it off, the frightening noise continues. When the beam is broken, the system uses the GSM network to give the user a warning call. Data is supplied to close the shutter and safeguard our goods when the system is activated. It is among the most cost-effective security devices available for safeguarding our possessions. This system requires extremely little electricity and is very capable.
