Elizabeth Watson started the topic Cannot Connect to Internet with SIM in the forum Mayfly Data Logger 2 years, 2 months ago
I’ve completed two Mayfly loggers, each with a ClariVUE 10 turbidity sensor connected. I used the DRWI_DigiLTE sketch to set the Logger ID, arrange the variable list, and input the UUIDs. However, I keep getting the message “could not wake modem for clock sync” on both Mayflys. The data for the sensor is shown on the serial monitor and it states…[Read more]

Hello!
Thank you for your response! I finally have the sketch uploaded.
I am now having an issue with the cellular connection. When I ran the sketch, it said “could not wake modem for clock sync” and then it let me know that it would be saving to the SD instead. How can I fix this?
I tried making sure everything was in the correct placement…[Read more]

Hi,
Has anyone setup their Mayfly data logger to monitor HABs in ponds/lakes? Right now, we are manually collecting the samples and trying to see if doing continuous monitoring would be beneficial.
Thank you.

You need to either upgrade your ModularSensors library from 0.34.0 to 0.35.0 or downgrade your SD fat library from 2.2.3 to 2.1.2.
All the dependent libraries are updated all of the time and not all versions match with each other. It’s best to download the libraries as a package from the ModularSensors releases page on GitHub. That zip file…[Read more]

Hello,
I’m currently trying to change the logger ID, input the variable list, and input the UUID List, but the sketch (DRWI_DigiLTE) keeps failing to compile. I’ll include both the error message as well as the sketch. I am at a loss with how to fix this and would appreciate any thoughts/suggestions! Thank you!

Scott Ensign replied to the topic Fetching MMW data from one sensor? in the forum Monitor My Watershed 2 years, 2 months ago
@tahicksonstthomas-edu: @srdamiano developed a way to query the Monitor My Watershed database for a specific parameter and specific time/date range. This is a huge improvement over using the Download button to retrieve your data, because you can limit the timeframe of data being retrieved and thus speed up the response. See Sara’s code here for R…[Read more]

Hey Scott Thank you the suggesion! I am finishing up a django web-app so folks can implement alarms with rain pauses without any coding. I will be sure to include srgdamiano‘s code to make things more efficient!
Here is a demo of the alarm app if anyone is intersted!

Hi Andrew. Thanks for sharing this code; I hope others have been able to implement this. @brianjastram recently asked if an “alarm” feature would be built into Monitor My Watershed (hopefully someday as resources allow). Until then, I suggested that your code might benefit from the work @srgdamiano did to specify parameter and time/date range…[Read more]
