Portable radon measuring probewith rechargebleaccumulatorallows to watchradon results remotely over wireless mobile network of Internet of Things (IoT) SIGFOX. The probe can be placed anywhere in the world where this mobile networkhas coverage(https://www.sigfox.com/en/coverage).The probe autonomously sendsin regular intervals measured result over wireless network SIGFOX to web serverwhere is possible to view and download results via internet and internet browserinweb application TESLA -MONTES. Coupled with delivery is charged wireless connectivityandwebappplicationregular servicefee. Configuration of probe and setting regular interval of sending are made over USB port and application in PC. Probe includes GPS module for better localization in wider measurement networks.
Probeis designed for continuous measuring of radon concentration. Portable probe basis is a measuring chamber with a semiconductor photodetector. Radon enters the chamber by diffusion through the input filter on the bottom of probe. The probe measures in autonomous and time continuous way. It processes results every 2minuteintervals and from this counts radon concentration (1 hour moving average -average of 30 2-minute process intervals). The probe sends results to server and saves time records inits internal memory (typically at an interval of 1 hour). Next saved valueto internal mamoryis time record of measuring energy spectrum (typically at an interval of 12 hours). The probe can be switched on/off by switch. LEDs „STAT“ a „CHRG“ indicate current status of probe.
Radon Probe can be operatedby these ways:
SIGFOX: Thanks to its independent battery power, portable radon measuring probe supports flexible placing options within monitored structures. Accumulator will last for more than 1 year after full charging. After switching on probe immediately starts measuring and sending results over wireless mobile network SIGFOX to server and the same time the results are saved to internal memory of probe (every hour default). On server it is possible to view or download results over internet connection and web page of application MONTES in internet browse of your PC (https://montes.tesla.cz).
USB: After switching on the probe immediately starts measuring and saving results into internal memory too. Using USB cable is possible to download results to PC continuously during measurement or at once at the end of measurement from internal memory of probe.
