Dan started the topic PAR issue with Mayfly in the forum Mayfly Data Logger 2 years ago
Hello,
I am working with a team measuring a host of variables off of mostly SDI12 sensors using both the newest and older Mayflys. We have run into an issue measuring PAR on our Mayfly logger stations. We are using analog Apogee SQ 100 sensors. We get data from the sensors/code, but the output values are about 10x too low. The relevant code is…[Read more]

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]

Thanks for posting your code, I edited your post to put it into the “code formatting” window that you can use when pasting code into our forum. It’s the little unlabled icon that looks like this: “<>” in the toolbar above the text entry box.
Your issue is caused by an error on line 186. It should look like this:

I uploaded the “SDI12/b_address_change” sketch and the address of the sensor is correctly assigned at “2”. My sketch is below. I modified the DWRI CitSci code for the ClariVUE. Thanks for taking a look!

When you power up the ClariVUE10 sensor, we’ve found that it take a few seconds to warm up before the Mayfly can “see” it. So when that sketch cycles through all of the available numbers and letters, it usually doesn’t see the ClariVUE until the second loop through.
So when you first connect the sensor from the factory and run the sketch, it’ll…[Read more]
Shannon Hicks replied to the topic Linking two Mayfly Boards Together in the forum Mayfly Data Logger 2 years ago
For the past year we’ve had 8 stations using SDI12 CTD sensors and Yosemitech wipered turbidity sensors together on one prototype Mayfly using the EnviroDIY RS-485 half-shield. It also works with other generic modbus adapters too. We’ve had no issues with not being able to read the sensors or with dropped readings. I’m attaching the code below…[Read more]

I used the Mayfly 1.1 board and the sketch below. Thank you for helping me!

Shannon Hicks replied to the topic Turbidity Sensor Information/Questions in the forum Environmental Sensors 2 years ago
When you changed the SDI12 address of the turbidity sensor to “2”, did you use the same Mayfly board and the “SDI12/b_address_change” example sketch that comes with our libraries, or did you change the address with a different board or instrument?

There’s an example of using an Arduino as an SDI-12 slave in the Arduino SDI-12 library.
