Thank you James!

OK, thanks for that clarification.

@fisherba My March order has the stereo plug.

@fisherba – Thanks for sharing this! I’ll be very interested to learn what Meter tells you.

I see what you mean on their product page: “When used with the ZL6 data logger, you won’t require an additional sensor for measuring—and referencing—barometric pressure.”

However, both the sensor manual and the Integrator Guide in the Downloads secti…[Read more]

Thanks @aufdenkampe – really appreciate that update, and all of the hard work by you and the team to fix and document these issues!

Note that the lost data appears to extend beyond May 7th, with very large data gaps each day from the 8th through 12th. The images attached below show these data gaps for 3 of our sites, with the UTC timestamp when…[Read more]

We are also seeing the data gaps that I believe @thomas-schanandore and @movingplaid have reported above across all 3 of the stations that I’ve checked.

In particular, there are large gaps (9- to 24-hours) every day since at least May 5th, followed by data resuming at 12:30UTC across every station. This suggests that something is failing on the…[Read more]

Hi All,

Just checking in to see if there is any news about the status of MMW. I haven’t been able to find relevant issues in the ODM2 Github site, so thought I’d share here what we’re seeing on MMW:

• The big Download Sensor Data button returns a Server Error (500).
• No sparkline plots are displayed.
• The 3 buttons for each variable are…

Hi Dan,

I’m curious whether it’s possible to identify Gen 1 vs Gen 2 Hydros21; are they labeled? I’m wondering what I’ve got.

Thanks,

Matt

Ok, I see. Thanks so much for taking the time to provide all these details – very helpful!

Best,
Matt

Thank you both for those details!

So to be clear: if I have only 1 SDI-12 sensor on the bus, and it’s at address 0, it should work properly with ModularSensors, even if I’m averaging 6 readings and collecting conductivity, temp, and depth each time. Is that correct?

Thanks Anthony. That warning is pretty clear. But I wonder why that’s a constraint.

It looks like “0” is a valid address according to the SDI-12 spec, and Meter supports it. Perhaps there’s something in ModularSensors that doesn’t like it. Scanning through the code, I don’t see anything right off.

@srgdamiano
Hi Sara, any advice on the question above, about powerUp/powerDown vs. wake/sleep?

Matt

Thanks to both of you for your responses! I think I had just figured out the cause of my problem right about the time you were posting them, but needed to continue refining and testing my code before replying.

What’s working now is:

1. In the sensor’s setup() function, set trigger pin to an output
2. at powerUp(), set pin HIGH
3. at wake(), run the…

Trying to track down and eliminate my my Mayfly’s excessive power draw during sleep, I rebuilt my circuit to use the Mayfly’s onboard ADS1115 via voltage dividers, but got the same results; my sleep current is still around 6 mA. However, I discovered that if I disconnect the Turner’s wiper trigger wire from D10, sleep current drops to around…[Read more]

@shicks The previous thread about I2C power that I’m aware of was when I learned that the jumper on the I2C grove port needs to remain in the constantly-powered position, otherwise the Wire library crashes, at least with certain sensors, including the Turner.

I *think* my Mayfly is sleeping: All LEDs switch off, if that means anything. If I…[Read more]

@shicks Thanks for those details. I wonder whether it could be the turbidity sensor, rather than the Mayfly, that’s actually drawing power, but I wouldn’t have thought it could do that while (or if) the Mayfly is sleeping. A bit more about my circuit:

I’m powering the Turner from Mayfly’s switched 3V3. The Turner’s analog output is 0-5V, which…[Read more]

Hi Neil,

I’m powering the Turner Turbidity Plus via the Mayfly’s 3.3V, and its average current draw during wiper cycles is 109mA.

Thanks for sharing your wingboard. As far as wiring, I have some of the EnviroDIY protoshields that I plan to use. I’m interested in how, physically, you connected the Vbat to your ADC for measurement. Are you using…[Read more]
