Automated Street Light
Nowadays there is wastage of electrical energy as we observe that normal street light are in switched on
condition in normal daytime but don’t you thing that our street light should have brain so we have
implemented automated street light where light turns on when there is darkness and automatically turn
off when there is presence of light.
Here we have used ldr (light dependent resistor) which senses the amount of intensity of light passing
through it and gives signal to relay when to turn on or off the light by microcontroller arduino.
