Intelligent IR based Automatic highway lighting system

The high way lights will be monitored manually which in turns is a waste of huge human power wastage at the instant when proper monitoring is failed. This drawback can be overcome by implementing a sophisticated automatic monitoring system through which high way lighting can be monitored automatically before the sunsets and they are switched off the next day morning after there is sufficient light on the roads. But the actual timings for these high way lights to be switched on are when there is absolute darkness. There is provided an infrared sensor unit for deactivating an electrical appliance when left unattended b its ser. When a person in the field of vision of the sensor detects the presence and activates highway lighting system. If it is day time the lights get OFF this operation can be performed by light sensor (LDR).
