LASER SECURITY ALARM WITH MIRROR REFLECTION CIRCUIT SCIENCE MODEL KIT
Brief 
The project is a fully assembled and working model.
The Science Model is designed on White Paper which is labeled neatly on a Soft Plywood Base.
This Model includes a Laser Diode which is powered to emit strong laser beam. This beam is deflected at an angle more than 180 degrees using reflective mirror and is made to fall over a LDR (Light Dependent Resistor).
Based on the LDR Sensor signals which are amplified using NPN Transistor, the Alarm is controlled. If any intruder passes through the entire Laser area, the Alarm turns ON.
Using Laser Reflection, we can enhance the range of Laser to secure the areas we require.
The model emphasis on the Laser Technology and enhancing the technology using simple concepts like Reflection to make the security system more viable and effective.
