Environmental Monitoring Using Wireless Sensor Networks(WSN) based on IOT

Abstract

In recent years, we have seen a new era of short-range wireless technologies like Wi-Fi, Bluetooth , ZigBee, emerging in front of us. The project aims at building a system which can be used on universally at any scale to monitor the parameters in each environment. Raspberry-pi and sensors collects all the real-time data from environment and this real-time data is fetched by the web server and display it. User can access this data from anywhere through Internet. Raspberry Pi works as a base station which connects the number of distributed sensor nodes via zigbee protocol. Wireless Sensor Networks (WSN) has been employed to collect data about physical phenomenon in various applications such as habitat monitoring. The Internet of Things (IoTs) can be described as connecting everyday objects like smart-phones, Internet TVs, sensors and actuators to the Internet where the devices are intelligently linked together enabling new forms of communication between things and people, and between things themselves. In wireless sensor network system, the sensor node sense the data from the sensor and that data collects the end tags, end tags send its data to the router and router to coordinator.
