I thought it was just my stations, but I see that all stations network wide are losing connection around the same time and for the same duration. Is there currently on going work being done on the site?

I’ll have to abandon this sensor.

thank you for all your help and sorry again for the miscommunication.

My knowledge with all of this is rather limited, to be honest. I thought you were just trying to talk between the Sensor and the MayFly. The current library that I am using is on GitHub at <https://github.com/NorthernWidget-Skunkworks/Walrus_Library&gt;

It does work when directly connected to the MayFly and Arduino Uno. IT does also work on the Arduino Uno (5v) when using the 3m cable.

I have verified the output with the MPL115A2 sensor that I have and the values are the same.

They said that the 3m cable works great with their data loggers on I2C protocol, but yes it would make sense to use an RS485 to just be sure that the signal won’t be lost over the length.

And of course it is only when I connect it via the 3m cable that the values do not output.

It sounds as if Northern Widget is not willing at this time to do any more trouble shooting with…[Read more]

It is probably the same firmware you are looking at. I am requesting also the I2C registers and commands.

Do I simply upload to the mayfly with the sensor attached? Or is this code to be added in somewhere in my overall code (PlatformIO)?

That one I will keep. The other four they just sent, without first figuring out the problem. If they don’t work I will simply send the four back. Yes, frustrating. Two months of not getting anywhere and now I need to make the decision to figure this out on my own or switch to a different sensor. Maybe…[Read more]

The sensor does work when attached directing to the I2C port (via. grove cable) on the Mayfly at 3.3v. That’s great, but as you know, I need to run that sensor into the stream.

I left it up to Northern Widget to upload the appropriate firmware to the sensor before they sent the sensors, so that that process would be streamlined. I did read through their documentation on the firmware and, as you stated before, they…[Read more]

I have been working with Bobby and Andy Wickert over there on this and they gave me sensors with the appropriate firmware installed already. I did not have to install any firmware.

I have been working a company called Northern Widget out of St. Paul Minnesota regarding their water pressure sensor named the Walrus. It is connected via. a I2C port and they say it should work on any basic Arduino based board at 3.3 to 5.5 volts. We had so much trouble getting it to work that we had to abandon using it. The sensor works…[Read more]

Since the boards were not designed to have that capability, do you think it would be impossible to attempt to develop a way to add in a secondary board with a cellular modem that would act as the receiver and uploader for programming remotely? I have come…[Read more]

I am curious if any developments have been made on creating a way of programming the MayFly data logger remotely, without having to go out to the site to physically re-program? I am new to the MayFly data logger, so I apologize if this has already been developed or already has the capability, but to my knowledge and research it does not. I…[Read more]
