Hello, I just finished mounting all elements end carefully followed all of the nice assembly manual (except serial settings). I have powered the circuit with a 9V 300mA adapter. But after one hour I see only 00.00 µSv/h. With the "select" button, and "Buzzer & Led On", I  can hear the radiation detections and see the led blink. But the Count CPM stay 00000. Is there some minimum settings to do before mesuring any radiation ? Or where I am wrong ? Best regards Dominique

Hi Joost, Came across this project and was woundering if you happen to have any pcb for the project. Thank you and well done

I'm still waiting for the PCB, it may take a few days more since that virus ... as soon as the pcb's are fitted with the parts I'll post some pics. In the mean time you can have a look on github at the Eagle cad files, if somebody is interested I can post the Kicad files too. Grüss, Jacques

Nice work! I will use some of the code for my weatherstation. But I have one question. Where did you install the new sensors and the particle sensor? Do you have some images for me/us? That would be great!
