Indoor Air Quality Measurement and Uploading the Data over Web

This paper presents a system which is used to acquire the information related to particular area such as an indoor air quality measurement with the help of a sensor network, a processing unit and the provision of internet using a router. Primary aim is to provide a system of lower cost and reliable sensors providing information in order to perform continuous monitoring of air quality of air so as to indicate the factors that might cause asthma attack. System consists of a sensors which has the ability to measure the various environmental parameters such as humidity, carbon monoxide, temperature and will send the measured data to a processing unit and thereby over to the web with the help of a router. A software implication includes a client side application which is used to upload the measured information to the server with the help of internet. Raspberry pi is used as a processing unit which primarily processes the data coming from various sensors thereby it can be used to define the various alarm points. So this system acts as a HMI (human machine interface).
