The main objective of an internet of things is used to help especially challenged people and old age people to control electrical appliances.
In this paper we present a Review of Sonar et al.’s Home Automation using IOT, Sangle et al.’s Smart Home System based on IOT, Mali et al.’s Home Automation and Security using Arduino Micro-Controller and Thobaiti et al.’s Home Automation System based on Arduino Uno Single-Board Microcontroller. Finally, we have done a comparative analysis of all the above-mentioned methods.
