Online monitoring of WSN based air quality monitoring system

This paper describes a simple Wireless Sensor Network (WSN)-based air quality monitoring system (AQMS) for industrial sectors. The planned structure comprises a group of sensors (CO₂, Temperature, Humidity, LDR and LPG) that are deployed within the environment using XBee module. In this system, we proposed two sensor nodes, the arduino UNO microcontroller for controlling the data, XBee for wireless communication and one gateway node. The collected information from sensors is given as inputs to the analog inputs of the arduino UNO microcontroller. The sensor node collects the particular data from the environment and sends it wirelessly to the gateway node. The gateway node is interfaced to the LabVIEW by a VISA. All these data are displayed on the arduino serial monitor window and front panel of the LabVIEW. We can supervise the sensor parameter values and upload these values in web portal.
