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.

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.

I see it’s resolved. Awesome. Thank you all.

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.

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

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.

Yes, thank you. Here it is.

I tried just DS18Temp but that didn’t work.
The Celsius temperature from the DS18 is a reasonable 22.25 degrees.

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

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.
