Sigma Home: An IoT-Based Home Automation Using Node MCU

IoT (Internet of Things) based home automation systems have emerged and developed in recent years to remotely monitor and manage various appliances and gadgets. IoT can be connected through the internet as it is a device that helps make connections and monitor various devices and sensors. The paradigm proposed by us uses Node MCU which is an open source Wi-Fi-enabled microcontroller based on the ESP8266 chip, with IoT because it is simple and easy to interface with the network for home automation. To monitor various home devices like lights, temperature, humidity, and fan, different sensors are used. The data obtained from the sensors are then monitored through an Android application or a web-based interface, and with this the energy efficiency can be increased by controlling electrical fixtures through IoT. Here, the data recorded by sensors are fetched by the cloud for further analysis, perform different commands, and obtain intended result according to the requirement. This study proposes a novel system functioning, performance, and reliable solution for home automation. This system will make it a flexible and resourceful solution for IoT-based home motorization by providing a perfect experience with a minimum requirement of maintenance and also improving the quality of life by providing minimal cost, energy consumption, and sharp security. This research study focuses on the system in which multiple sensors are used and a layman can also get used to with this type of upcoming technology. Overall, the smart home automation system is scalable and provides a complete security to home, reduces human effort, and is also cost-effective.
