The hustling lives in today’s fast pace era has led to people undergoing stress with less time and more responsibilities. With the emergence of digitization, the above problem is approached with the solution of home automation. Home automation alludes to the controlling of home, which includes home appliances, home environment, home safety, home energy, and other domestic features, remotely or by the means of local networking, and it is gaining popularity at a very rapid rate today as it offers numerous benefits to its users such as time saving, cost saving, decreased stress, better immunity, better self-productivity and self-efficiency. Home automation can be efficiently achieved by the Internet of Things, which is a framework wherein physical objects are interconnected via the Internet to form a dynamic network infrastructure. Due to its synergistic and minimal effort nature, Wireless Sensor Network (WSN) brings noteworthy favourable circumstances over conventional communication techniques utilized as a part of the present IOT framework. This paper presents a detailed study of various smart home systems that are built on the IOT framework using Wireless Sensor Networks (WSNs) wherein the interconnected multiple devices including home appliances and various sensors such as temperature sensor, fire sensor, safety sensors etc., are monitored and controlled through a single or multiple smart device/s such as smart phone, laptop etc. either locally or remotely by the user. The heterogeneity of home automations is indicated in this survey in which various technologies that have been considered are ZigBee protocol, cloud computing, wearable sensors, and android-based and arduino-uno microcontroller based protocols.
