IOT BASED SMART LIGHT SYSTEM USING MQTT PROTOCOL

Now-a-days saving power is a big challenge. We need to use devices which are efficient, user friendlyand saves power. The devices having these factors are called “SMART DEVICES”. Thesesmart devices can be built my making use of Internet of things.The scope of this paper is about building a smart light whose brightness, on ,off , can be controlled by using MQTT protocol in which light can be controlled by the user who has subscribed for that topic sitting anywhere around, which saves power.
