The transmitted data is then received by the wifi module connected with the Node MCU. The data sent from the IoT Android App to the Firebase realtime database, which is hosted in the cloud. The core component of this “Smart Home Automation system” is Node MCU which is considered as a brain or controlling device of the system.
