        abstract = {This research paper analyzes that now a day’s security is an important aspect. Technology develops day by day in the world. Nowadays crime gang also improves their technology to carry out to cover a large area. We know laser light goes too long distances without scattering effect. It’s additionally obvious just at the source and occurrence point, in any case invisible. These two properties help us to develop a modern security system, which may name a “Laser Security System.” When any person or object crossover the laser light, automatically the buzzer starts ringing. Laser beam goes through long distances without scattering effect and the ray is almost invisible. The project involves the use of ESP32, Laser light, Buzzer, LDR, PIR sensor, and a simple program. And also we use the Blynk app which is connected to the ESP32 microcontroller. From this app, we can enable or disable the security systems. With this equipment, we can easily set up security that makes sound or commotion when it distinguishes any sporadic action or can be part of a much bigger security or any other automation system which can alert the owner.  },
