    Hello Vern,

    I see there was a downtime on April 23 and 24, but your unit’s transmission has been since uninterrupted. What was the problem?

    Unfortunately the offline units are being disconnected due to various reasons, and I say “unfortunately” because that’s harder to fix than a technical problem.

    There have been only a few failures so far (4-5 units), some related to the power supply (not affecting the unit), some to an inductor inside (needing replacement) and some to failing geiger tubes (again needing replacement).

    Overall these units have proven to be highly resistant, and you should have no issues with your either. https://www.uradmonitor.com/?open=110000D0

    Hi Dave, this is a nice question and the answer is YES.

    The PCB’s have been designed with a connector where you can add a clicker. See it in the picture attached.
    I recommend the self oscillating 3V piezo buzzers. Here’s an examples:

    You will also need a firmware upgrade, as by default the digital output pulses on that connector are disabled.

    Currently the server holds only 1 in 10 readings, to lower the load. This will be soon changed to an average of the 10 values instead.

    What you got there is clearly a radiation spike. How often did you notice these?

    Works fine for me. But let us know if you continue to experience slow performance.

    Hi Lars,

    Is the current location ok? https://www.uradmonitor.com/?open=11000016

    Hi Mitch,

    IMO the additional enclosures are not needed, but they surely bring additional protection to the unit. To answer the questions:
    – The model A units were effectively tested in the -20 .. +65 Celsius interval with no impact on their functionality. That is -4 .. +149 F .
    – No. Thin plastic enclosures are transparent to Gamma radiation.
    – No, but care should be taken, as increasing the temperature over +65 might degrade the magnetic properties of the ferrite core, resulting in the high voltage inverter being unable to supply the required voltage to the Geiger tube. If you compare existing charts, you’ll see the direct link between temperature and the inverter’s duty cycle parameter – quite interesting.
    – Free air no, but outdoors yes, as that is where a possible contamination can come from.
    – Interesting question. In case of a nuclear incident, fallout covering the ground will be registered by the detector. Intensity varies with the square distance to the source. So the height requirement is in place to ensure consistent response all across the network, but if such an event occurs, this is the last thing to worry about. Snow can be disregarded, even if it affects the height, it is temporary.

    Hi Mitch, indeed, this could prove useful! Will see for the next firmware upgrade.

    That’s a good approach, however I’m not sure on how often the monitoring site calls the API.
    If too often, it might trigger the DoS protection and get ignored (interpreted as a sigh of deliberate server resources consumption).

    EDIT: Indeed if there is no recent data, the JSOn answer will show an empty array (no matches).

    With the increasing number of sensors, on the map you’ll be able to select the parameter of interest.

    There are only a few changes between the two. I wouldn’t regret it.

    Thanks for the idea. Do you have some samples on such data? How complex is it?
