Hi Sara, any other thoughts on what I can do to troubleshoot this issue?

I’m added a new capability for the Mayfly to program its internal EEPROM with geographical specific pieces of information.
When a site is visited, this will allow the retrieved uSD card to be replaced with a blank uSD card.

For multiples sites that don’t have modems, and the readings…[Read more]

I have not, I’m still getting this when I monitor the output:
“Attempting to connect to the internet and synchronize RTC with NIST
Could not connect to internet for clock sync.”
This is exactly what I have for the lib_dep portion of the…[Read more]

@movingplaid for the basic EC sensor above, and 10bit ADC and running at 2minutes sampling – which is way too fast for a simple DC switched EC sensor got a pretty good result. Graph below.
Next stage is to run it overnight, and for simplicity will graph it on MMW

Hi Robert, be happy to, and I’ve just finishing up a ModularSensors class.
just thought I had posted here, and it hasn’t shown up, so trying again – here are the core…[Read more]

@neilh20 re: #13915
I had seen that post on the $3 EC meter several months ago and experimented with building a variation of that sensor but had little success. Thought that it might be better to buy something that already works, to better understand it, an not try to reinvent the wheel.
I would love to see what you come up with for…[Read more]

Hi…i could say about the functionality of the sensor which can help you to choose the one rather than looking for inexpensive sensors. The current through the liquid will be that voltage divided by the effective total liquid resistance through the hole and back around the outside of the pair of cores. The cylinder inside the cores will…[Read more]
