@jamesp I wonder how the systems are faring?

A follow up – I had this running for about 6 weeks last year.

The code is in my fork is at  https://github.com/neilh10/ModularSensors/tree/release1/examples/samd_log_display_mmw  and is available to the main at any time.

For test purposes, I positioned the temperature sensors in my office, attached to different areas round the heating vent, w…[Read more]

@bibhutibikramaditya Exactly what output are you getting?  You’re not asking for data in your script, so you should only be getting a response like “00013” not any data values.

Suggestions:

• Confirm that the data pin of the Hydros 21 sensor is plugged into the correct pin (2)
• Confirm the sensor has power
• Confirm that you’re serial port…

We wrote Program for Interfacing Hydros sensor 21 with Arduino Uno board using SDI-12 interface and saw the result on serial monitor . We tried a lot in implementing a program for connecting sensor directly to the digital Pin (Pin7/Pin2) of the Arduino UNO board using SDI-12 interface and viewing the result on the serial monitor. We found only…[Read more]

Hi Jim, a shop account will be automatically created when you pay for a subscription and you’ll receive an email with your username and a link to reset the password. The shop account will allow you to manage and modify your subscription. Thanks for your support of Monitor My Watershed!

I tried to sign in today to pay for the GMI medium plan at $49/mo.  The store doesn’t recognize any of my credentials.  Do I need a different account?

Are you using PlatformIO or the Arduino IDE?  In PlatformIO, you can add it to the build_flag section of your platformio.ini file. Add -DMS_SDI12_NON_CONCURRENT right below the -DSDI12_EXTERNAL_PCINT line in the example ini file.  If you’re using the Arduino IDE, you need to open up SDI12Sensors.h and add the line #define MS_SDI12_NON_CONCURRENT a…[Read more]

Thanks for the quick response Sara. I have not used the build flag. Flags are not something I am familiar with, and I don’t know how to use or adjust them properly. Where would be the appropriate place to make this adjustment in the library?

Have you tried using the -D MS_SDI12_NON_CONCURRENT build flag: https://envirodiy.github.io/ModularSensors/group__sdi12__group.html.  Some SDI-12 sensors don’t properly support the concurrent mode that ModularSensors uses by default.  That could by why they work individually, but not all together.

@neilh20 Thanks for your questions. Please refer to the Terms of Use for details concerning use of Monitor My Watershed. @srgdamiano commented on the likely cause of missing data from September 26. We are continuing to improve Monitor My Watershed’s response time and performance; we will share details in early 2024.

I finally dug into this.  As I commented on GitHub, I think this loss must be related to a server update or hotfix.  The server did get the data, so it might be recoverable. I doubt it’s related to the older issue.

Hi Shannon. So I just received a few more panels. The stereo jack cables are going in relatively easily with these. I think I received some damaged hardware, causing the stereo jack cable to be very difficult to get plugged in. And causing a bad connection to the logger.

@paulwilson Yes, the payment page for Monitor My Watershed subscriptions will begin accepting payments on 01 January 2024. Thank you for supporting Monitor My Watershed!

I’m very much a fan of ModularSensors and the discussion board as a place to be real with technical issues.   I do so appreciate the unique place EnviroDIY has been curated to be, to try some remote wireless terrestrial monitoring. Its the nitty gritty of environmental monitoring and the engineering it takes.   Its tough to find out what these ser…[Read more]
