Hi all,

I am testing a Mayfly setup with a HYDROS 21 CTD and a Yosemitech 511-A turbidity sensor. The Turbidity sensor is working well, but the CTD seems to intermittently dropping in and out (see attached MMW plots).

Any thoughts on what might cause this? I have set the CTD address to channel 1 as per instructions. I did notice that the ‘sdi12_address_change.ino’ script went haywire until I removed the Modbus WingShield, so I wonder if the Y511-A is interfering with the CTD signal? The Y511-A is set to address 0x01 as per factory settings.

Thanks in advance for your help.

James

Does your Modbus wingshield do any level shifting of the CTD’s SDI-12 data line? Is there anything on the wingshield tied to whatever Mayfly pin you’re using for the data line (I’m assuming D7)?

Hi Shannon,

Yes I am on D7 for the CTD. I am using the default pins for the mayfly modbus wing (https://github.com/EnviroDIY/Mayfly-Modbus-Wing/tree/master/Modbus-Mayfly_WingShield):

Communication is hardwired to Mayfly digital pins 5 & 6, which enable use of the AltSoftSerial library.
Read more at our Notes on Arduino Streams and Software Serial.
Power to the RS485 to TTL Adapter comes from the Mayfly's switched 3.3V power.
Power to the sensor(s) comes from the Mayfly's switched 5V power supply, which can then be optionally boosted to 9V or 12V depending on the requirements of the sensor.

I have switched my pin for the HYDROS 21 CTD from D7 to D11, but I seem to be having the same issue. It’s worth noting that I don’t get -9999 values when plugged into my computer. Could it have something to do with power?

My code is below.

I had a lightbulb moment today that seems to have fixed my problem. I switched the 3.3v jumper to 5v. Success!! I guess it was brown-out.
