Scott Ensign commented on the post, How Do EnviroDIY Monitoring Stations Compare With USGS Stations? 2 years, 3 months ago
Hi James; thank you for providing this input and emphasizing the challenges of using turbidity as an absolute measure of a physical property. This issue has been explored and reported on in the past, but Rob […]

Scott Ensign replied to the topic Turbidity Sensor Information/Questions in the forum Environmental Sensors 2 years, 5 months ago
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).

Scott Ensign replied to the topic Using AltSoftSerial with Mayfly in the forum Mayfly Data Logger 3 years, 3 months ago
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]

Scott Ensign replied to the topic Using AltSoftSerial with Mayfly in the forum Mayfly Data Logger 3 years, 3 months ago
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]

Hi Vinay and Cheryl. It is great to see your teamwork sharing and troubleshooting! Just a tip: you can more easily share Arduino sketches on this website by posting questions and answering them in the Mayfly Data […]

Scott Ensign replied to the topic How to dump contents of file on SD card to serial in the forum Mayfly Data Logger 3 years, 4 months ago
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]

Fiona, if you haven’t already found it, check out Adam Gold’s blog about using the Mayfly with Atlas Scientific sensors. Adam’s github has documentation about a carrier board that may involve isolation.

Hi Dan,
We recently did some internal testing of this issue and will post results soon. We don’t have a “fix”, but we did measure this behavior to guide our own interpretation of data.

<p class=”crayon-selected”>Hi James,</p>
I’ve used Atlas Scientific’s RGB sensor on lagrangian river drifters in the past. The application is written up in Limnology and Oceanography (or see this video abstract of the article). I’m attaching two simple sketches for using this sensor with the Mayfly Data Logger. The first (…AutoMode) just prints…[Read more] -

Thanks, Neil. That’s helpful to know that ThingSpeak via Modular Sensors might be a better option for this user’s purposes. He has an interesting classroom laboratory application that I’ll encourage him to share if he is able to pilot it at his college.
