IOT Based home automation using Node MCU

The present paper was about IOT based home automation by using Node MCU. The Electrical equipment in the house was communicate with the network devices like Wi-Fi, Zigbee Bluetooth ect., for allowing users to control through smart phones. This devices uses Node MCU microcontrollers and several sensors like temperature sensor, Humidity, fire sensors and motion sensors and also this utilizes the 4 Chanel Relay Module which functions as a switch to turn off or turn on electrical equipment in the home. One of the key benefits of IOT-enabled home automation is the ability to control and monitor a wide range of devices and systems from a single, centralized location, such as a smart phone or tablet. We can enable or disable the functionality of appliance by means of IOT from remote environment.
