Home Automation using ESP8266 Wi-Fi Development Board

Computer Science Engineering

The fast growing world needs various technologies to improve quality of life. By the virtue of blooming automation industry and wireless connectivity, all the devices within the home can be connected. This improves the comfort, energy efficiency, indoor security, cost savings of the home. Small and constrained embedded devices are used to remotely monitor the conditions within home and control the home appliances. The Internet of Things is a network exchanging the data/information between the devices having Internet connectivity, sensing and computing capabilities. This work uses the ultra low power consumption ESP8266 system on chip board operating 2.4 GHz ISM band for wireless connectivity. The relay circuitry is interfaced to ESP8266 NodeMCU board using the GPIO pins in order to control 220 V supply power outlet, wherein domestic appliances such as lights, fans, air conditioning system, and so on may be controlled remotely. The WLAN SSID & password allow only authorized persons from the home to control such appliances. The Android app has been designed and generated making use of the open source web application to control the domestic appliances using any Android Smart phone.
