Abstract
Technology is a never-ending process. This paper presents a low-cost flexible and reliable home automation system with additional security using ESP32 Development Board, with IP connectivity through local Wi-Fi for accessing and controlling devices by authorized user remotely using Android Smartphone application. The proposed
system is server independent and uses Internet of things to control human desired appliances starting from industrial machine to consumer goods. To demonstrate the effectiveness and feasibility of this system, in this paper we present a home automation system using Node MCU microcontroller ESP32 as a connectivity module. It has built in Wi-Fi chip which is connect itself with internet via users Wi-Fi router with internet connectivity. It has some I/O pins to control input/output devices such as, push switches, relay module etc. There is a Bluetooth module to communicate locally. This
Bluetooth module communicate with ESP32 using its serial port. There are 4 channels relay module connected with ESP32 as an output control device, it mainly ON/OFF the load circuit. We used Google Firebase database to store our current status of loads. This
project helps the user to control various appliances such as light, fan, TV etc. We have tested our system through conducted experiment on various environmental conditions
