Hi @shicks (and thanks @neilh20),

Thanks for that. I am using a Yosemitech Y511-A with a Hydros CTD (Gen 1). My code is fairly similar to yours. I notice that you use pin 22 to power the Y511 (line 145) where I have ‘-1’. I also don’t see the line ‘<span class=”crayon-i”>AltSoftSerial</span> <span cla…[Read more]

Hi,

I am having problems with the interference between MODBUS and SDI12 sensors on a Mayfly v0.5 board. I can remove either one and the other works perfectly, but together I end up with around 20% -9999 values, usually for the SDI12 CTD. I am virtually certain this has to do with the home-made modbus wing that I have built for this system. I…[Read more]

Hi Scott, interesting article! Regarding turbidity, Rob Davies-Colley, an academic here in NZ has been doing some research comparing nephelometers, as turbidity thresholds are often written into environmental […]

Hi Neil,

I would only need 5 at this stage. I would connect it to my Yosemitech turbidity sensors and potentially Yosemitech pH sensors as well.

Regards,

James

Thanks Shannon. Please let me know as I will likely order a few of these and some mayfly 1.1’s.

Appreciate the hard work.

Hi Shannon,

Do you have any idea when the RS-485 half shields are likely to be in stock?

Hi @ddrummonrtp and @aufdenkampe,

I’m interested in using these mDot modules to connect with the Helium network.

Dale or Anthony, would you mind posting your code to integrate mDot modules with the Mayfly?

Thanks for your help!

Regards,

James

@sgfulton Thank you!

I will give this a crack.

@shicks, thanks for your help anyway Shannon. @aufdenkampe, any insight on the code above would be greatly appreciated.

@neilh20, yes all setups are the same. Some work fine, others have issues with dropping out. I have spare Mayflies and a spare CTD, but no spare turbidity sensor. Did you ever end up producing your Mayfly wings for the 0.5…[Read more]

Hi @shicks. I’m just wondering if you saw anything in the code above that might be causing this problem?

James_NZ replied to the topic Hydros CTD-10 Regularly Dropping Out (-9999) in the forum Environmental Sensors 7 months, 3 weeks ago

Hi @shicks and @neilh20

I’m leaning more towards an interaction with the MODBUS wing. I had one station that produced -9999’s constantly when the Turbidity sensor was plugged in, and operated fine when I removed the MODBUS wing. This drove me nuts until Anthony pointed me towards the complex loop code where I set the Turbidity sensor to low a…[Read more]
James_NZ started the topic Hydros CTD-10 Regularly Dropping Out (-9999) in the forum Environmental Sensors 7 months, 3 weeks ago

Hi all,

Around 50% of my sites have a problem where the CTD drops out on a regular (not predictable) basis. This results in -9999 values which may persist for a few readings before returning to normal.

I still get a data record out of this, but the resolution is lower and I would like to fix it if possible.

Has anyone experienced this…[Read more]

Okay, after a good night’s sleep I decided to tackle this again and I think I have fixed it. I simply added a line before the internet connection loop:
```
modem.modemWake();
```
It’s now logging to MMW. Please let me know if this is fundamentally wrong or will cause problems in the future.

James_NZ replied to the topic Interference between HYDROS CTD and Yosemitech Turbidity Sensor in the forum Mayfly Data Logger 8 months, 3 weeks ago

Hi @aufdenkampe,

I have followed your advice and I think this is working, i.e., I am no longer having problems with -9999 values for the CTD.

However, the complex loop code is preventing publication of data to MMW. I’m sure this is something simple, but I can’t seem to figure it out.

I have tracked the issue to the line where the code checks…[Read more]

Hi all,

Is there any way to edit the data record for a site on MMW? I have had some problems with one site and would like to delete a section of the data record that is erroneous. I can’t seem to find an option to do this anywhere?

Thank you Anthony. It sounds like this may be the problem. It seems strange that I have 9 of 10 sites operating perfectly, but this site refuses to play nice. I will try your solution when I get some time over the Christmas break.

Have a great Christmas and New Year.

Hi all,

I have a frustrating problem at one of my sites where the turbidity sensor seems to be interfering with CTD readings resulting in -9999 readings for all CTD measurements. I’m using a DIY MODBUS shield for the turbidity sensor, and when I remove that the CTD reads perfectly. This puts me in a situation of only being able to read the C…[Read more]

I still have the same issue for my sites too.

Also TSA only seems to show battery voltage and Mayfly board temperature.

Hi all,

I have just installed six sites which seem to be calling in reasonably reliably. The data is showing for each measurement but only EnviroDIY sensors are show a sparkline and are able to be examined in TSA. I can download a dataset from each site and analyse it in excel but would like for the community to be able to see data in TSA.
