The kit Atmega based street light control is very useful to automate the street lights on roads, or the lights in stadiums, especially in stadiums where the total intensity of the light is assumed to be constant. Here the LDR (Light Dependent Resistor) senses the environmental intensity of light and accordingly regulates the voltage at its output. At the output, we have DC bulbs/LED MATRIX connected whose intensity changes accordingly.

This Atmega based street light control kit is the sensor LDR that has the property to change its resistance according to the intensity of the light. As the intensity of light falling at the LDR increases, its resistance gets decreased, and so on. This property is used to monitor the change of light. The controller regulates the LAMP in accordance with the measured light intensity.

In the kit Atmega based street light control, there are two modes of operation manual and automatic (selected through control switches and represented via LED indication). In manual mode, the user can regulate the light via knob while in automatic mode light will be regulated depending upon the environment condition automatically.
