A pollution monitoring unit for monitoring local air quality

摘要

This invention relates to a personal device for monitoring pollution gases and particulate pollution. This device is designed to alert and warn the user that the local environment is polluted and to take the necessary precautions. This present invention relates to a personal, portable, handheld and wearable detector system. The pollution monitor in one embodiment includes a particulate sensor and a chemical sensor or sensor array for detecting pollution gases. The sensor outputs are analyzed by a microprocessor and if the pollution levels are higher than the set thresholds this will warn the user by an audible and visible alarm. The alarm signal can also be output via a communications module to a local network via a wireless link. This system will have a low operating power and a compact small size to facilitate its function as a personal pollution monitor.
