Analysis of environment changes using WSN for IOT applications

Wireless Sensor network is architecture with three components in it — Nodes, Gateways and Software. The nodes are used to monitor environment by spatially distributing them and by interfacing with sensors. All acquired data is transmitted wirelessly to gateway which in turn can process it independently or can be connected to a host system which can collect, analyze, process and present data using some software. IOT is an physical object network. Objects can be vehicles, buildings, devices, switches, and other items. The network is embedded with electronics, sensors, and softwares. Network connectivity is enabled to allow these objects to collect / acquire data and process whole data as per application requirement [1]. In this paper we present a system to monitor environment of soil with the help of WSN. Various sensors are used and data is acquired from each of them. Attention is needed for a farmer to protect his field from different disasters caused either by human or by nature. Human effort is not sufficient and also very expensive to pay for a worker. Here we are using few sensors to monitor the farm those are temperature sensor, moisture sensor to check whether the field is dry or wet and a LDR to verify the lighting at that place. All these will be monitored and sent to the authorized persons email id in the form of mail. So that necessary action can be taken accordingly within short Spam of time.
