Wi-Fi Portable Solution for Distributed Radon Measurements

摘要

This work presents the development of a system which monitors the radon level, using a PIN diode for detecting the radon particles and a data processing module with Wi-Fi communication capabilities for the transmission and management of measure- ment results. This solution represents an inexpensive, easy to use, portable radon de- tector which can be used for monitoring the radon level in a specific location or for being a part of a distributed monitoring system. The detector can send radon level mea- surements to a computer or a smart-phone or can be a part of an ad hoc network of sensors. Data can also be stored locally and therefore the system can be used in envi- ronments where wireless connectivity is not available at all times. The main advantage of the developed system is the long lifetime which may reach up to one or two years, due to the fact that it runs on batteries and that it uses ultra low-power Wi-Fi.
