I do believe my DO sensor right now is fried from another mishap, so I am trying to get just the Turbidity sensor to work currently.

Oh sorry I just saw your other comments. Thank you! I will get to testing that.

I just took off my DO sensor and am now testing the Turb (Y510) alone, I just moved the RXD and TXD from the adapter to pin 5 and 6. However when I do so only the TXD LED lights up when TXD wire is in pin D5 and the RXD LED will not light up, but when I plug the D6 and reverse the two pins only RXD LED lights up. So, I cannot get both LEDS to flicker and either way 5 or 6 the sensor is outputting -9999. So currently either one of the two LED lights are steadily on not flickering.

Thank you so much for answering me I have been stuck for quite some time.

To answer your questions, I am running them separate because my Y504 Sensor requires 6+volts and needed a DC step up booster board and the Y510 sensor needs 5volts. Would it still be possible to put them on one RS485 and power supply?

I am unfamiliar with the NeoSWSerial, is there a place on envirodiy to look up how this one work and how to code it in and the pins etc.?

I had not touched the addresses for either of the sensors, correct, me if this is wrong, if I put the sensors on one power supply and adapter, they have to have separate addresses? So at least one needs to be changed through yosemitech library, but If I keep them separate and use the NeoSWserial for at least one, I can keep the two sensors at the original addresses?
I am using an Amazon ALMOCN TTL to RS485 Adapter Module 3.3V 5V 485 to TTL Signal Single Chip Serial Port Level Converter Borad with RXD, TXD Indicator. It does not say flow control at all, but it does say it can match the module.

I am still slightly confused on your last paragraph, is that referring to the Sv5 pins and/or the mayfly ports set to 5v?

 

Again, thank you!

I am going to using just the SD card for my project. I thought I would need a unique UUID regardless so that was my first attempt at trying for that. So if I am using just the SD I can ignore the Non-unique UUID message? what about the invalid UUID, can that be ignored too?

[Liz]

In my code I have the yosemitech sensor set up but in the serial monitor it does not address the sensor at all? Why would that be. I am very new to programming especially the Mayfly data logger and platformio.
