In this project, we are
controlling Street lights using IOT. There is various combination of energy and
all of them are alternative to each other like solar energy, wind energy, bio
fuel, fuel cell, etc. But the need of controlling of hybrid energy system
arises when it is installed for domestic or commercial purpose. At this point
IOT plays an important role in controlling system. The main criteria being
switching between the two sources of energy i.e. solar and wind energy without
any inconvenience through a website using Nodemcu module. The data is
transmitted wirelessly to cloud through Nodemcu module which controls the
sources of energy. The transmitted data is controlled remotely using IOT. This
enables user to have flexible control mechanism remotely through a secured
internet web connection. This system helps the user to control the sources of
energy, manually and remotely using smart phone. This system is very efficient,
cheaper and flexible in operation
