Publications

IOT BASED SMART SECURITY AND HOME AUTOMATON SYSTEM
IEEE
This paper represents home automation with full security and controlling the home appliances using wireless communication as Wi-Fi.
Implementation of an Advanced Irrigation System with Logical Output
IEEE
In this paper an illustration of an automated system of farm irrigation and soil moisture control by Arduino is proposed. This automated system for irrigation identifies the moisture content present in soil and automatically toggles the switching of pump when the power is supplied. An appropriate usage of irrigation system is substantial and it is essential to maintain suitable water content and avoid shortage of water due to lack of rain and spontaneous use of water, to avoid wastage of water.
An Implementation of Motorized Wheelchair for Handicapped Persons
IEEE
This wheelchair is able to detect any obstacle or crack on the path towards the direction of motion and alerts the user with the help of sonar sensor and IR sensor. The enriched results of this project fabricated a path for further advancement of this technology and finally being manufactured.
