Abstract

Internet of things is getting developed rapidly. Each and every day new devices are getting connected with internet. This stream of IOT brings new experience in our daily life. Connecting our wearable devices, gadgets, keys etc can make our own home a new world to us. Every component of our house can communicate with us through IOT. But connecting each device with internet requires costly devices like Wi-Fi modems, GPRS modems etc. This makes connecting each component with internet quiet expensive. In this paper we have developed a cost effective way of connecting each component with internet quiet expensive. In internet. As most of the household components are stationary and close to each other they can be connected with each other through mesh networking. A central device will receive their information and transmit it to internet. The cheapest way to create a mesh network is to use NRF protocol and a WIFI modem does the rest of the work to upload each and every data of this network to internet. In this project there are several nodes regarding their purpose like sensor nodes to collect temperature, humidity, co2 gas quantity and monitor through internet. Control nodes turn on or off AC, fans, lights of house and detection node to find out keys, sun glasses, and small objects.
