This content provides an overview of Node MCU which works as  the heart of the a smart home automation system designed to operate lights and fans and detect gas and electricity leaks by ensuring personal safety from the use of gas and fire sensors which provides alert messages to the house owner. Node MCU based Smart home automation system receives instructions from the user and executes task as per the users instructions. At last, the RFID block is connected to MCU, then motor drive communicates with the gear motor as the valid RFID the gear motor rotates and door will open and close . The main purpose of the home automation is to work according to the user’s instructions and to provide intimation back to the person.
