This Project Intelligent Emergency Light will turn on the Emergency light only during the Dark condition. Ordinary emergency light will be switched ON during the power failure condition. So that if there was a power failure in day time the ordinary emergency light will also be switched on. So there is a loss of power. Our system will continuously monitor the light falling on the LDR and when there was no sufficient light over the LDR & there is a power failure then it will switch on the Light. So that the place at which the circuit was connected will always in Bright. And if there is a power failure then the power to drive the emergency light was taken from the Battery supplied with the circuit. The Whole system was controlled by the Microprocessor 8085. It continuously monitors the Light in the Room and it will switch ON the emergency light if there is a power failure and the Room was Dark.
