Portable environmental monitoring system

Abstract

In this modern world of 21st century, the development of new technologies is rapid than in the past. People are more concerned about new industries and businesses. As a result, environment has become less important to human beings all over the world. Due to increasing number of factory and industries, the pollution of environment has increased from past days at a significant rate. There are various types of environment pollution caused by human beings, for example, air pollution, sound pollution, radioactive pollution, water pollution, soil pollution etc. Now if we analyses some of the survey data on environment pollution of Bangladesh, we can see that the rate of air and water pollution is too high. There are a lot of reasons behind this situation of pollution. One of the major reasons is there are no such way for the general people to know about the current data of any environmental units. General people cannot generate ideas about different environmental values of air, water or soil which may help them to understand the current situation of environment. Now if they have a modular device which can collect data from the environment and one that analyses those data, then people can easily understand the situation of any particular environment. To solve this issue, we approached to building a portable environmental monitoring system which can collect data from the environment automatically using distinct sensors and can store those data on a web server. The main features of this system are light weight and portable and it can also be accessed by any authorized person from anywhere in the world. There are several sensors integrated into a tiny PCB board to minimize the size and increased portability. The on field experimental data helps us to verify the system practically and measure the efficiency of each sensor and subsystem.
