IR based street light Essay Example IR based street light Essay IR based street light Essay Nowadays, it became essential for people work during nights and returning back to homes late nights, so safety parameter to be implemented to a great extent on highways. This can of this lighting system must be taken into account. The existing system is like, the high way lights will be monitored manually which in turns is a waste of huge human ewer as well as precious time in addition with 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 sun sets 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. This project gives the best solution for electrical power wastage protection. Also the manual operation of the lighting system is completely eliminated. There is provided an infrared sensor unit for deactivating an electrical appliance when left unattended by its user. The sensor unit includes a passive infrared sensor distance of the electrical appliance An Infra-Red (R) sensor is an electronic device commonly used in security lighting, and burglar alarm systems. When a person in the field of vision of the sensor, the sensor detects the presence and activates highway lighting system, If it is day time he light gets OFF this operation can be performed by light sensor (LDR). E best achieved by implementing proper lighting system on highways. The efficient monitoring This project uses regulated IV, mama power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the AC out put of secondary of 230/IV step down transformer. Bridge Rectifier Filter Circuit Power supply to all sections Regulator Step down TIFF
