An Integrated Environmental Monitor

Abstract

More and more pollutions have been made since the Industrial Revolution occurred in the late 18th century, and these environmental problems are not confronted seriously until the previous century. In recent years, people face these problems and start to pay attention on monitoring our living environment by self. Simple and practical instruments are required in measuring environmental parameters and pollutions. In this purpose, we developed an integrated environmental monitor (IEM), based on Arduino platform. This monitor is composed by several sensors, includes measurement of temperature, humidity, atmospheric pressure, air quality, sound strength, solar ultraviolet (UV) radiation, etc. All sensors are modular, which means these sensors could be added/removed depending on different requirements. A GPS receiver is also build-in to get real time and position, and all the observed data are recorded on a SD card. The advantages of this monitor are low-cost, low-power consumption, high accuracy, and multi-function. It’s suitable for education and can be a good household environmental monitor in the future.
