We’ve made the software for this project available on GitHub, and deployable to a Rasberry Pi via balenaCloud using the button below: We recommend this button as the de-facto method for deploying new apps on balenaCloud, but as an alternative, you can set this project up with the repo and balenaCLI if you choose. If you want to pipe the results to a text-file, you can run the script in the following way: Change SN with the 10-digit serial number, and change SAMPLE-PERIOD to a numerical value of your choice. In this example we’ll just use the motion event to make a popup appear on the Raspberry Pi’s monitor. Each detector is sealed into radon-proof pouch. This guide has been tested with Raspberry Pi 3 Model B, Raspbian Stretch (November 2017), bluepy 1.1.4 and Python 2.7.13. Run the attached script: pi@raspberrypi:~ $ python read_wave.py xx:xx:xx:xx:xx:xx. Let us know how it went on our facebook page! The radon measurements are given in Bq/m3 and the maximum value that can be read by the script is 16383 Bq/m3. There are a couple snags that you should watch out for, though: If you're still struggling to get NOOBS on your SD card, this tutorial is pretty comprehensive and should answer most of your questions. The last matter of business is to actually use our motion detector to trigger cool events! Zelf radon en thoron verminderen. One example of this is Z-Wave's array of smart sensors. UPDATE: Check out our Github account for the most recent scripts. The large can will serve as the ionization chamber (in the radon detector). Within the application, select on the upper left corner ‘Add device’ being sure to select ‘Wifi + Ethernet’ to set up the wireless network. Primary business objective is the development and sale of precision instruments through a radon-related research. Radon Detector!! to find the process id of the currently running motion instance.
