BrianJastram started the topic I am currently unaffiliated with and organization. in the forum Monitor My Watershed 2 years, 7 months ago
I created an account on Monitor My Watershed and selected my organization “Mississippi Watershed Management Organization”. I have deployed a rain gauge and set up the site “SAVPW-RG” but on the second line of the site page after Organization it says “I am currently unaffiliated with and organization.” How do I get my organization to populate that…[Read more]

BrianJastram started the topic BME280 Altitude Pressure in the forum Mayfly Data Logger 3 years ago
Why are the altitude/pressure data from my BME280 so wild? I got a range of -138 to 740 meters. It was stationary during this time. No actual change in altitude.

If they wrote to the SD card in the lab but not the field could it be a power supply issue?

BrianJastram started the topic Board Temperature Spike in the forum Mayfly Data Logger 3 years, 6 months ago
I have a ProTrinket that counts rain gauge tips and an Xbee LTE that are both connected to my solar powered Mayfly. On March 10th the board temp spiked up from the 40sF to the 70sF, the battery voltage spiked from 4.4v to 4.8v and I got a -9999 for a tip count. Then the temp. battery and tips went back to normal. This happened about 50-60 times…[Read more]

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

BrianJastram replied to the topic Connecting Bare Wire Sensor to Jack Adapter in the forum Mayfly Data Logger 3 years, 7 months ago
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.

BrianJastram replied to the topic Connecting Bare Wire Sensor to Jack Adapter in the forum Mayfly Data Logger 3 years, 7 months ago
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, 7 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, 7 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, 11 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 4 years, 1 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.
