Laser Farm Security System

Agricultural fields are often exposed to security threats such as crop theft, animal intrusion, and unauthorized access, especially in rural and isolated areas. Conventional security methods like fencing and manual guarding are either expensive or ineffective for continuous monitoring. This paper presents a Laser Farm Security System that uses a laser beam and a light dependent resistor to create a virtual security boundary around the farm. When the laser beam is interrupted, the system immediately detects the intrusion and activates an alarm to alert nearby individuals. The proposed system is simple, cost-effective, and energy efficient. It is suitable for small to medium-sized farms and helps reduce dependency on manual supervision while providing real-time security.
