    Nice one. It's clear there are some winter projects developing ... and that last link even has a basic weather station for Gavin

    Alternatively, someone needs to design a WiFi/GPRS interface for the current system.

    Hi Fatshark
    I was going to ask Gavin to shift these posts to another thread maybe Electronic hive monitoring or something but his mailbox is full
    Must be all the Merry Xmas messages

    You could send one of these into the hive after the varroa

    If only! Yeah, I'd thought of doing that myself so it will probably happen. When there is a bit of free time. I'll clear some inbox space too.

    Great set of posts, they deserve a home of their own.

    This is another interesting candidate with (it would appear) all the features built in GSM etc
    Linkit One costs £57 though so not cheap

    (The official Arduino GSM board is £50 but there are clones for about half that)

    Hmmm ... tempting feature-set, but poor reviews andnon-compatibility with Arduino issues. Call me old fashioned, but the bleeding edge can sometime be a bleedin' nuisance. I'd usually choose a well-established user-base, good documentation, Mac-compatibility (issues here by the looks of things with the Linkit) and a programming language I at least recognise - perl, python, C ... especially when stepping into the unknown.

    Hi Fatshark
    Take your point just looking around
    The raspberry zero might take a while to be available
    It has low power consumption for its spec

    Ordered a tested AT tiny with some connectors from these guys £3-00 inc delivery
    It came next day (today)and they provide all the links for getting it up and running
    http://www.ebay.co.uk/itm/x1-x5-Digi...8XFYE65kGp81Pg
    Haven't done much with it yet just soldered the headers and added it to the boards selection in Arduino software
    Run a blink sketch after a bit of fiddling with Linux permissions

    Excellent DR. I expect you've seen this Arduino-based temperature and relative humidity sensor. It's based on the DHT22 sensor which they claim isn't very accurate (but don't indicate how inaccurate ... however, someone who has lots of time on his hands has checked the temperature accuracy of these sensors and claims ~0.5oC)). They also have a very much more accurate version (different - much more expensive - sensor) which are based on these boards at 5 for £13 (or about a quid each untested). They make this write to a small SD card, with a claimed battery life of up to a year.

    In contrast, I've been very low tech ... I'm busy making soft set honey and printing labels for Christmas

    Hi fatshark
    for most purposes the DHT11 looks OK I think ( 2% temp 5%humidity) its about £1.50
    The (DHT22 0.5%temp 2%) humidity is about £3.50 and the bees will probably mess them up anyway

    The pro version of the AT tiny boards has a CH40 USB which a lot of the Chinese Arduinos have fitted
    I haven’t used one myself but you need to get the driver for it online extra agro possibly
    I don’t like downloading stuff like that reminds me of Windows

    This is an UNO clone with a 16U2 usb to serial so same as the genuine board I have one and it seems v good for £5.00
    UK based deliver in a couple of days

    Ps well done on the honey front I forgot what it looks like Lol!

    Would any of the devices you're looking at work for putting a microphone into a hive and streaming the sound into the house/office? That's the type of monitoring I'd most like to try. I briefly tried the Arnia monitors but was disappointed to get graphs rather than raw sound.

    The issue with streaming is power consumption. You would drain a battery powered one in no time. You would probably need a WiFi connection as the GPRS costs would be astronomical.
