    The Homepage shows Voice as Chooseable Sensor but no Data.
    Wy is the Option shown if there is no such Sensor in my Device?
    Thanks,

    Hi Jan-Peter,

    I have the Model A and it does not have the VOC (Volatile Organic Compound: https://en.wikipedia.org/wiki/Volatile_organic_compound) option, but other models do (shown in colorful circles on the map in screen shot below). My take is that while some of us do not have all the available sensors, the map choices reflect all of them so we can all see the data of those who do have multiple sensors in their units.

    I can´t find a Model with Microphone therefore this data and option have no point.
    Secondly I don´t think a Micro in this Devices is a good Idea at all.
    There are enough spying Devices such as Google Echo, Handys with apps such as Siri or Alexa and so on around.
    We don´t need to give the NSA more Data.

    I need to clarify something – your original post you said you were concerned about the Noise option and I had forgotten there was a new “noise pollution” option, which is why I went on about the VOC. I thought maybe you meant the VOC, so, my apologies for my confusion. I’ve asked Radu in facebook about the sensor for the noise pollution monitor.

    Hi Guys, sorry for the slow reply.

    A new hardware revision of the A3 model (v105) comes with a noise pollution sensor. This cannot be used to record voice, as it is limited to just a few samples per minute (Voice goes in the kHz range, that means a few thousands of samples per second).

    The noise pollution is a critical issue in cities, affecting life quality directly, this is why we need to address it as well.

    as for the other questions:
    “The Homepage shows Voice as Chooseable Sensor but no Data.”
    The option is called “Noise”, not voice.
    The selector is generic and it applies to the entire network, regardless of the those that don’t have a particular parameter (those will appear as black squares).

    “Wy is the Option shown if there is no such Sensor in my Device?”
    Later A3 devices will all have the noise pollution sensor. The option was added in software, however older A3 units won’t be able to serve this data.

    Thanks
    Than it would be OK.
    You´re Right in seeing the Problem.

    So I have HW 104, can I retrofit the noise sensor?
    I live in an area that is close to a major airport, and there are planes flying over our area several times a day, so this would be a nice addition.

    I got a brand new A3 / HW version 103 just about a week ago. Since it should be from the latest production batch – why do I not have the latest HW version?

    The noise sensor was added in HW105 . This is not yet released, except for a single, experimental unit: https://www.uradmonitor.com/?open=8200006F&sensor=noise

    We will see more of these in the future.

    Units 8200006C, 6D, 6E, 70, 71 and 72 however, do have the HW105 PCB, but the sound sensor circuit is not populated. For those of you interested in enabling this functionality, it is possible to add the missing parts. I can provide guidance on that.

    Sounds good … I got the 72. Can you please then help me to enable sound sensor circuit.

    I have 5B so am I completely out of luck, or is there any way to add the sound sensor to this one also?

    @eldaria: I’m afraid not.


    @urs    : you need the following components:
    3x Resistor SMD0805 1K
    1x Resistor SMD0805 100K
    2x Resistor SMD0805 1M
    1x Capacitor SMD0805 100pF
    1x Capacitor SMD0805 10nF
    1x Capacitor SMD0805 100nF
    1x Capacitor SMD0805 10uF
    1x IC SMD MAX4466EXK+T
    1x Electret Microphone 6×2.2mm like these: http://g03.a.alicdn.com/kf/HTB1Xj5.OVXXXXbTapXXq6xXFXXX1/Free-shipping-30PCS-6-2-2-Microphones-font-b-capacitive-b-font-electret-font-b-pickup.jpg

    The components will need tweezers, soldering paste and a hot air soldering station. Careful not to damage the other parts of the board with the hot air. The circuit/pcb layout is as follows:

    @urs: I have loads of spares from placing an order for mine (most items came in strips of 20 or more). If you haven’t yet purchased them and are considering happy to mail a set at no cost. Assuming this thing allows you to send private messages if interested.

    @ShimmerNZ private messaging has just been added. Thanks for the excellent suggestion!
