Abstract

Monitoring air pollution including the contents of VOC, O3, NO2, and dusts has attracted a lot of interest in addition to the monitoring of water contamination because it affects directly to the quality of living conditions. Most of the current air pollution monitoring stations use the expensive and bulky instruments and are only installed in the very limited area. To bring the information of the air and water quality to the public in real time, it is important to construct portable monitoring systems and distribute them close to our everyday living places. In this work, we have constructed a low-cost portable RF sensor system by using 400 MHz transceiver to achieve this goal. Accuracy of the measurement was comparable to the ones used in the expensive and bulky commercial air pollution forecast systems.

Highlights

As modern technology advances rapidly, the environmental pollution has been progressing very fast
As much as the development of technology has satisfied many people on their basic living conditions on foods, clothes, and dwellings, people became more aware of the quality of living conditions and started investing to achieve the clean environment
The simplest method to monitor the deterioration of the environment is to sample the air, the soil, or the water from the contaminated area and to analyze them in the laboratory

Summary

Introduction

As modern technology advances rapidly, the environmental pollution has been progressing very fast. The simplest method to monitor the deterioration of the environment is to sample the air, the soil, or the water from the contaminated area and to analyze them in the laboratory. This method often takes too much time and efforts in sampling and testing. By locating many stations in the wide area and employing advanced communication technology, effective monitoring of the environmental contamination may be achieved. We developed a low-cost portable RF sensor system to measure the air pollution and water contamination in addition to the real-time location information [1,2,3,4,5]. Our work contains the original concept to add the location information to the environmental pollution information collected from our scientifically engineered portable system
