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 ..

Thanks Scott.

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…[Read more]

Mayer, if the CR1220 battery powering the internal clock is low on voltage this could be causing a time mismatch and no connection during the cellular connection sequence.

Fiona, I am using a system I designed to suspend my CTD sensor one foot above the bottom of a pond by attaching the sensor to a float which is anchored to a concrete block (see attached photo).

If you have a mending plate on the back of your logger box you can use a long hose clamp to attach it to the dock.

I see it’s resolved. Awesome. Thank you all.

It did seem to make a difference in the short term but the problem started again. My latest fix was to ground the analogue signal cable to the battery negative. I’ve done this now on 4 rain gauge systems and it seems to be very reliable. Should have done it sooner.
