  As you say from 2nd sept – something changed, after that it looks to me like its is triggered by the temperature changes. Its just a visual analysis, but also using the conductivity. With a rain event the conductivity also typically changes, and of course temperature can change.

  For daily diurnal cycle after sept 2 the temperature starts varying…[Read more]

  Sure. https://monitormywatershed.org/sites/VCRP1/

  Best way to view it is with time series visualization. Exclude interruption of pattern by a rain event and having the sensor out recently over a recorded reading.

  Just wondering if you could post a link to where the data is being collected, and look at it as a system.

  Can you email me the entire .ino sketch that you’re using with the board.

  Everyone has been out of stock of that particular battery for the past 6 months.  As you said, you can use the Adafruit 6600mAh pack (https://www.digikey.com/en/products/detail/adafruit-industries-llc/353/5054549), or you can use the single-cell 2200mAh cell (https://www.digikey.com/en/products/detail/adafruit-industries-llc/1781/5054543).  As l…[Read more]

  Hi,

  Thanks for the quick reply! I am not getting any red lights on the modem at all. I have the Mayfly plugged into my pc right now and the only lights are the orange charge light, the USB/POWER lights, and D8 is lit up as green right now.

  The modem seems to be correctly seated according to the instructions. We previously were able to get this…[Read more]

  Does the red power light on the lower right of the modem turn on? If not, the modem isn’t getting power. Pin 18 should be the right pin number. I’m not sure why it wouldn’t be powering up. Have you ever messed with the solder jumpers?

  If the modem is powering up, you might have a baud rate problem. Try setting the modemBaud to 57600 even…[Read more]

  Also double checked hologram.io to check to see if the sim is active, it is. I’ve also tried swapping the battery out, taking the sd card in/out, and have messed around with

  const int8_t modemVccPin = 18;

  and have swapped it from 18 to -1 as per the commented code, but it has not worked.

  Hi,

  Continuing to run into a problem connecting our Mayfly to LTE, getting an error: “Could not wake modem for clock sync”.

  I’ve seen this posted a lot but I still can’t find any concrete reasons as to why I’m getting this error. I’m using the “DRWI_SIM7080LTE” sample sketch and using a HYDROS 21 to connect.

  I’ve generated, formatted, and…[Read more]
