- Abstract:
- In this paper an user-friendly and manageable measurement system for environmental monitoring and control applications is presented. The specific experimental case concerns the acquisition and processing of the exposure levels to environmental electromagnetic field (EMF). The proposed measurement instrument is equipped with a Personal Digital Assistant (PDA) device and a field probe sensing the electromagnetic field in high frequency range. The small dimensions make it a practical tool in order to monitor the pollution state in urban area. The embedded application allows user to acquire and test in real-time the field levels in order to verify their conformity with fixed exposure limits. The processing stage optimization is achieved by analyzing the influence of measurement uncertainty on the comparison process between measured values and tolerance limits. So, according to measurement result, a confidence level provides information on the response reliability about the compliance or non-compliance with the fixed thresholds. A final report on the PDA display shows user the general EMF trend and the possible limit overcoming happening. Then data can be transmitted to a remote client for further analysis, so designing timely appropriate intervention plans in order to safeguard population from potential hazardous situations.
