This paper presents the functional design and integration of a complete WSN platform that can be used to remote environmental monitoring and target for IoT applications. The system of physical object devices, vehicles, buildings and other items embedded with sensors, electronics, software and network connectivity that enables these objects to collect and exchange data, this is called IoT. IoT is estimated to generate large amounts of data from diverse locations. IoT is one of the platforms for today’s smart city and smart energy management systems. Wireless Sensor Network (WSN) is used to monitor environmental conditions such as sound, pressure, temperature etc. The application requirements are long lifetime, low cost, fast deployment, low maintenance; high number of sensors and high quality of service are considered in the specification. Low-effort platform reuse is also considered for the specifications and design levels for a wide range of related monitoring applications.


The Future internet, called as “Internet of things” is seen to be a worldwide network of interconnected objects with unique address having standard communication protocols. A system like sensors, RFID tags, computers, or mobile phones will be able to dynamically connect to the network, collaborate, and work efficiently to achieve different tasks. Including WSN platform in such a environment will open new directions or perspectives. Any physical system can be controlled and operated easily by using wireless technology if it is compared to manual operation. If this automation is considered for environmental monitoring, it responds very fast. Also it increases chances of secure communication, speed of the system operation. Human entered data was seen as a limiting factor for acquisition systems, cost and pervasiveness. Two main technologies are called as a key enablers for IoT are RFID i.e., Radio Frequency Identification Tag and WSN i.e., Wireless Sensor Network. While considering application field, WSNs plays very important role by collecting surrounding information and context. WSN helps to reduce physical efforts in the automated systems. WSN bring richer capabilities to IoT application for both sensing and actuation. The proposed system can be called as a smart system as it can measure parameters automatically. Sudden and gradual changes in environment had taken place in recent times because of human careless activities in relation to environment. This results in disasters which can cause harms to human lives. The system can intimate in advance to user about such causalities. This system also uses GSM module for the wireless control of environmental parameters. In this system, GSM network is used to give the status of each sensor connected to the controller on mobile. Applications and limitations of this monitoring system are discussed briefly.


Wireless Sensor Network is designed successfully and implemented for the purpose for which it has been designed. On observation of the performance it is concluded that the present system is reliable and variety of applications can be applied. Application parameters calculation and monitoring is precise and automatic even over the larger area. System can be monitor globally using uploaded data over internet. GSM is an alternative secure way to the internet. Parameters threshold can be changed depending upon the environment.
