BrianJastram replied to the topic Arduino NB-IoT for ISCO autosampler in the forum Infrastructure and Equipment 9 months, 2 weeks ago
Hannah,
I use Campbell dataloggers (CR800) to collect and send data from ISCO auto samplers to a database. The Campbell datalogger program also has the capability to accumulate stormwater flow data and initiate flow paced sample collection with the samplers via a SampleRequest command. I haven’t connected an ISCO 6712 to an Arduino but I’m…[Read more]

Mayer, if the CR1220 battery powering the internal clock is low on voltage this could be causing a time mismatch and no connection during the cellular connection sequence.

BrianJastram replied to the topic Installation in Soft Substrate/Docks and Buoys in the forum Infrastructure and Equipment 1 year, 2 months ago
Fiona, I am using a system I designed to suspend my CTD sensor one foot above the bottom of a pond by attaching the sensor to a float which is anchored to a concrete block (see attached photo).
If you have a mending plate on the back of your logger box you can use a long hose clamp to attach it to the dock.

BrianJastram replied to the topic Rain Gauge Tip Data Without Rain in the forum Mayfly Data Logger 1 year, 6 months ago
It did seem to make a difference in the short term but the problem started again. My latest fix was to ground the analogue signal cable to the battery negative. I’ve done this now on 4 rain gauge systems and it seems to be very reliable. Should have done it sooner.

The site (SAVPW-RG) was not created after mid-December. It was created closer to that Aug. 2019 date.

@heather, Thanks for checking.
Both accounts were set up before the mid-December release. The personal account was around 8/13/19 and the organizational account was around 10/3/19.

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 2 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 2 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 2 years, 6 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 2 years, 6 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.

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 2 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 2 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. - Load More
