LIGHT SENSOR DAY/NIGHT BASED DC MOTOR FAN CONTROL 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 Light Sensor called as LDR. LDR is connected to an amplifier BC547 Transistor.
Under Dark conditions, LDR will allow current to flow through BC547 Transistor which will amplify current for the DC Motor Fan. Thus turning on the Motor. So during Night, Motor will turn On and will turn off during Day time.
The entire circuit could turned on/off using a Switch.
The model emphasis on the importance of Efficient Automation System using Light LDR Sensors
