Discovery-Center,

I have attached some photos of the WQ monitoring buoy I built.

I added an LED beacon to make it visible at night. I’m using a 20lb. kettlebell as the anchor with a steel cable and 3/8″ nylon rope with cable ties holding them together to prevent tangling. I added a float to the CTD sensor to ensure it maintains 18″ of distance away from the weight. It’s working well.

Hi Kurt,

In regard to downward trending DO readings, contamination, membrane damage, and electrolyte, is there an anode and cathode on your probe that you can clean? I used to use a YSI galvanic DO meter that would accumulate tarnish, which I would occasionally sand off to improve the responsiveness of the readings.

I got it to work.
I edited the libraries and logging program to use the new sensor. https://github.com/brianjastram/GHWX/tree/main/GHWX4

I use Texas Electronics rain gauges https://texaselectronics.com/tipping-bucket-rain-gauges/ and a ProTrinket with the Mayfly for my precipitation monitoring. It looks like your rain gauges also operate with a reed switch.

I’ll try it. How do I log in?

Thank you for your advice. I changed the I2C address at line 34 in the AOSongAM2315.cpp. I got this output ..

Current logger time is 2024-05-13T15:02:43-06:00
———————–
EnviroDIY Mayfly at EnviroDIY Mayfly reports batteryVoltage is 4.715 volt
SensirionSHT4x at I2C_0x44 reports relativeHumidity is 39.09 percent
signalPercent is calculated to be 97 percent
SensirionSHT4x at I2C_0x44 reports temperature is 24.72 degreeCelsius
AOSongAM2315 at I2C_0x38 reports temperature is -9999.0 degreeCelsius
AOSongAM2315 at I2C_0x38 reports relativeHumidity is -9999.0 percent
———————–

So it looks like the address change is in effect but sensor values are still -9999.

Do you have any advice or ideas for my next troubleshooting effort?

[BrianJastram]

Thanks Scott.

[BrianJastram]

I see. Thank you for your work on this.

[BrianJastram]

@heather, I can confirm the fix is working and add a kudos for the swift fix implementation from LimnoTech. Thanks!

I tried registering a new site yesterday and today with no luck.

I also just paid for a subscription so that would be out of the way.

Any suggestions for registering a new site?

Thanks.
