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?

Thanks Scott.

[BrianJastram]

I see. Thank you for your work on this.

@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.

Hannah,

I use Campbell dataloggers (CR800) to collect and send data from ISCO auto samplers to a database. The Campbell datalogger program also has the capability to accumulate stormwater flow data and initiate flow paced sample collection with the samplers via a SampleRequest command. I haven’t connected an ISCO 6712 to an Arduino but I’m interested to know if you know how to enable an ISCO program remotely because I haven’t discovered a way to do this. My approach has been to have the sample program on a separate datalogger that controls when the sampler samples based on sample requests from the datalogger.
