@millerlp: are you seeing current data now? We are aware of the issue but it should be resolved now. If you are still seeing issues can you report them to help@monitormywatershed.org?

On a Mayfly V1.0 Rev A3, is power to the 2X10 analog header controlled by pin 22 or is the header constantly powered? I’m trying to utilize power from the 2X10 analog header while the grove ports are not powered (pin 22 is low) if this is possible.

@wcb_data: you can access csv formatted data for a parameter at a site by specifying the parameter ID. For example, I can retrieve all of the specific conductivity data for site https://monitormywatershed.org/sites/CR_UTFZ/ with this url: https://monitormywatershed.org/api/csv-values/?result_id=5081

You can grab this url for any parameter at a…[Read more]

Given the popularity, complexity, and expense of turbidity sensors, the team here at the Stroud Center has compiled a snapshot of some commercially-available options that may help people decide on the best option. This table likely excludes other vendors and models; it is intended to summarize those sensors that we have recently used or…[Read more]

Jake, I deleted a “test” site of mine last week in MMW and it worked as expected (no error).

Problem solved. As Sara has noted before, the AltSoftSerial can only use pin 6 on the Mayfly for receiving and pin 5 for transmitting. So, while the sketch worked with Software Serial as shown above (and would have worked by defining pin 6 for transmitting and pin 5 for receiving), my pairing of the sensor rx and tx wires to the Grove jack was…[Read more]

I’m struggling to use AltSoftSerial in place of Software Serial to connect an Atlas-Scientific Color sensor to a Mayfly. The script below successfully communicates and reports sensor data as expected with Software Serial (with lines 21 and 26 active instead of lines 22 and 27 as shown below). As shown below I don’t get any data from the sensor.…[Read more]

This sketch is also available here: https://github.com/ScottEnsign/SDoutput. I’d welcome input and refinement.

Hi @Selbig. Here is a very simple sketch that prints a file from the microSD card to the serial monitor. It might be too rudimentary for your purposes, but thought I would share it here. Notice the line “// SD.remove(“datalog.txt”);” is commented out. Uncomment this line to DELETE the file specified instead of printing it to the serial monitor. I…[Read more]
