Shannon, yes, the outer jacket color I received is black. Good to know about the possibility of sensor damage or bricking.

They did not give me a pinout, I just did trial and error of figure it out. I think next time I’ll purchase a stereo jack adaptor and try connecting it to the Mayfly that way.

Shannon, I received 3 Meter CTD-10 (HYDROS 21) sensors this week and they did change the wire colors. For me brown is power (VCC) and orange is data (D2). I also had to use the b_address_change sketch to change the SDI-12 address from 0 to 1.

There should be no u in Maxium in line 194.

I tried just DS18Temp but that didn’t work.
The Celsius temperature from the DS18 is a reasonable 22.25 degrees. -
BrianJastram replied to the topic Calculated Variable Celsius to Fahrenheit DS18 in the forum Mayfly Data Logger 3 years, 2 months ago
Now I got it to be 33.8 F by replacing
float TempF = TempCFromMaxiumDS18_Temp*1.8+32 with
float TempF = true*1.8+32 -
BrianJastram replied to the topic Calculated Variable Celsius to Fahrenheit DS18 in the forum Mayfly Data Logger 3 years, 2 months ago
Awesome, thank you. That solved the error. I was wondering about my variable array because I saw the format of the variable array in the baro_rho_correction sketch and it was more bare bones.
Now I’m puzzling on the -17966.20 Degree F output I’m seeing in the serial monitor. I tried adding true to the ds18->getValue(true) but that didn’t work. -

BrianJastram replied to the topic Rain Gauge Tip Data Without Rain in the forum Mayfly Data Logger 3 years, 5 months ago
Shannon, great job moving the science forward. It seems like your line of experimentation could lead to a simpler way to count rain gauge tips and transmit the data to MMW possibly without using a ProTrinket. Maybe if a tip happens while a cellular transmission is happening the transmission could be interrupted, the tip could be counted, and then…[Read more]

I’ve got 5 solar powered Mayflys deployed with ProTrinket tip counters connected to heated and non heated rain gauges reporting their data to MMW via Digi XBee3 – RF TXRX Cell 4G LTE AT&T Verison – XB3-C-A2-UT-001 modems. These deployments range in length from 2-14 months. Within the past few months two of these setups have started reporting tips…[Read more]

BrianJastram replied to the topic Logging Mayfly with Decagon SDI-12 Sensor in the forum Mayfly Data Logger 3 years, 7 months ago
scornia,
I was having the same problem with the address change sketch (using the Atom PlatforIO) so I tried using Arduino IDE and that worked. It saw the SDI-12 address of 0 at pin 7 and I successfully changed it to 1 and now I’m getting values from the Meter CTD-10. Good luck. Let me know if you have any questions.

scornia,
In May I had this exact setup deployed and working. I used a WiFi modem and was logging to MMW. It slowly lost power because it was in too much shade and eventually I replaced it with a U-20 level logger. Now I’m working on this setup again and I’m having a similar issue to yours; the address change sketch just loops and my serial monitor…[Read more] -

Sara, Thank you (sigh of relief of knowing why it wouldn’t work). That was my goal and now I know it shouldn’t be. That is very helpful. No wonder I couldn’t find an example anywhere.

How do I get my DS18 to work on an I2C Hub plugged into my I2C Grove port? It’s currently working on Pin 5 and I have the DeviceAddress but when I plug the DS18 into the I2C hub I can’t find a pin that will work.

Shannon, can you share your code for enabling the Mayfly to keep track of the cumulative total?

I don’t know how to do that but I think I could figure it out. Can you point me in the right direction?
Best Regards -
BrianJastram started the topic Accumulating Precipitation Graph in the forum Monitor My Watershed 4 years, 5 months ago
Is there a way to plot precipitation on Monitor My Watershed (MMW) as an accumulating total? I’m getting the spiky plot showing tips/5min. but I’d like to show tips/24hrs.

BrianJastram replied to the topic Data Dropped Between Mayfly and MMW (2.4%) in the forum Monitor My Watershed 4 years, 5 months ago
I checked the SD card from one of my cellular enabled Mayflys and was surprised to find 14 .csvs created in the last 20 days. Some of the breaks (with missing data point) in the .csvs match with a missing data point on MMW. One of the gaps on MMW is between voltage values of differing digits after the decimal, 4.745 and 4.73. So now I’m seeing…[Read more]
