AIMS– Find the speed at which the turbine
will turn – Find at what distance will the
prototype be from the source, 3D Desk Fan
– characterizing the turbine speed as the prototype is affected by a controlled wind source Horizontal Arrangement Vertical Arrangement

LDR Sensor LDR Sensor
LDR-Light Dependent Resistors that are very
useful in light/dark sensors. Typical resistances (at dark surrounding environment) ranges up to a 1 Mega Ohm extreme but drops dramatically almost instantaneously after being illuminated.
LDR Values ObtainedAmbient Light Resistance Value (F325
Room Light)= 6.88k ohmsDark Light Resistance Value (By covering
the upper optical sensor)= 244k ohms

Current Measurement Current Measurement
The set up is done by connecting a 200 ohm resistance (load) in series with the Multi-Meter in order to make a suitable connection for the configuration.
The experiment is done on both the motors available as connected in the prototype available.
