Advanced smart sensor interface in internet of things for water quality monitoring

An interfacing device plays important role in data acquisition systems. However, different signal types of sensors in general are limited by these devices. Gradual improvement of IoT has lead to a revolution in the wireless communication; this scenario facilitates various applications from environmental monitoring to industrial management. Wired networks are mostly used to transfer data by connecting sensor. It is advantageous as it provides reliable communication system for instruments and controls. But connecting the sensors with a wired network will be costly hence low cost wireless technologies are much needed to cut down the cost. A novel approach is proposed in this paper to design smart sensor interface for water quality monitoring in IoT environment. Different sensors are available for water quality monitoring which are used to check the quality on following parameters i.e. pH, dissolved oxygen concentration, turbidity and temperature etc. IoT provide interface to monitor and operate remotely from anywhere and anytime. Intel Galileo Gen 2 board is used as interfacing device in our proposed system. The system performance is tested on water environment monitoring and improved results are gained.
