AIM:
The main aim of this project is to design Density
Based street light controlling system.
PURPOSE:
The main purpose of our project “Density based
Street Light controlling” is to control the switching of
Street Lights automatically according to the density.
MOTIVATION:
Whenever the traffic is less i.e., the density of traffic is less, there is
no need to street lights to be glow at maximum intensity. A minimum
level o f intensity of lights is enough to see the roads.
To develop the above system we are using Embedded systems.
DESCRIPTION:
Mostly the roads are one way, so, it will be easy to calculate
the no. Of vehicles entering into a particular length of road and also that are leaving the road.
By this we can also calculate the total no. of vehicles that are present
in Particular length o f the road. For this we are using IR sensor. When an vehicle is entered on to the road the sensor detects the vehicle.
The Major Features:
28 KB (3,710 words)
4k Bytes of in-system Reprogrammable flash memory
Fully static operation: 0HZ to 24MHZ
Three level programmable clock
128 * 8 –bit timer/counters
Six interrupt sources
Programmable serial channel
Low power idle power-down modes
OPERATION OF THE PROJECT:
The IR Transmitter will transmit the IR rays, if these are
not received by IR Receiver. Then it will be noticed that an obstacle will
be detected on the path of IR rays.
This indication will be given as input to the micro controller.
Whenever, this happens, the micro controller will increment the count of
the no. o f vehicles that are detected by IR sensors. And thus the street light
Switches accordingly.
CONCLUSION:
The project “DENSITY BASED STREET LIGHT SWITCHING BASED ON SENSORS ” has been successfully designed and tested.
Secondly, using highly advanced IC’s and with the help of growing technology the project has been successfully implemented.
