  Shannon Hicks replied to the topic LI-710 Compatibility in the forum Environmental Sensors 11 months, 4 weeks ago

  The electronics themselves are rated up to 85 degrees C (185F).  We’ve never had an issue with the boards at high temperatures, it’s just that the lipo battery packs don’t really like extreme temps (either hot or cold) because they don’t charge efficiently.  Just doing a cursory check of random stations on Monitor My Watershed in warm climates, I…[Read more]

  Thank you for your reply. Do you anticipate the coding to be intensive (more than a few hundred lines)?

  Yes, I would be powering the LI-710 with a deep cycle AGM battery.

  On a different note, what temperatures has the Mayfly and LTE Bee been tested in?

  I would be deploying it in an area where temperatures surpass 115 f.

  A Mayfly Data Logger should be able to communicate with a LI-710, but someone would have to write a specific SDI12 library file of commands for that sensor, using the example command info in the manual.  It also looks like it’s a continuously-powered sensor, requiring 0.125mA at 12v, with up to 2A during initial startup.   I assume you’ll be po…[Read more]

  Eric Booth replied to the topic Logging data from Milone eTape in the forum Environmental Sensors 12 months ago

  Sorry for the delay. I’m planning to use it in an H-flume that has a maximum depth of 0.45 meters. It looks like precision is listed as 0.25 mm but I’m okay with accuracy closer to 2 mm.

  And thanks for the sensor range info. I’ll plan to install the eTape in a probe well attached to the flume that extends below the flume entrance elevation. I…[Read more]

  I am thinking about buying a LI-710 Evapotranspiration Sensor https://licor.app.boxenterprise.net/s/3uehdcs2tkwhb120zm3l961pauvjhl9d

  I was wondering if I could use a Mayfly as a data logger for it without needing to buy a SDI-12 adaptor

  Thank you, Adam

  Good to hear. and definitely very interested in use with a flume.  What range of water depth measurement are you looking for and depth accuracy of measurement.

  Typically, because  ADCs are got good around 0.0V and rail – the Sensor range from 0.0 to full range, the Voltage range is from 10%Rail to 90%Rail (eg 0.3V to 3.0V for 3.3VDC rail) and t…[Read more]

  Thanks for the response, Neil. I’m basing the idea that the sensor is calibrated on the following response from Milone when I asked about the difference between the standard voltage divider setup and the other more expensive (+$45) output modules:

  “<span data-olk-copy-source=”MessageBody”>If you go with the standard voltage divider, each sensor…[Read more]

  Hi Eric – I’ve purchased and looked at using the eTape.

  I was just wondering what made you think they are “calibrated” – that is the “0.0” markings relates to a defined voltage.  Usually this is shown for a calibrated sensor.  Similarly for a Full Scale relates to a known Voltage.?

  looking at the graphs,  they describe “0-5VDC Linear Re…[Read more]

  neilh20 replied to the topic Abnormal power usage? in the forum Mayfly Data Logger 1 year ago

  Hello Elliot, gosh too bad for the experience. Its a core issue of how to ensure there is enough power, and then also recover from low power events.  However to be able to get some help its best to post the details of the two systems.  Need to phrase the problem with enough detail that some one else might be able to comment.  Battery size and so…[Read more]
