  Ah!  Some pieces are coming into clearer focus.

  Thanks!

  The only difference between the Gen 1 and 2 Hydros21 sensors is that the Gen 2 sensors need a little more time to respond to the SDI12 measurement command, which is hardcoded into one line in the MeterHydros21.h file within the ModularSensors library.  If you’re using the most recent version of ModularSensors, then your code will support both…[Read more]

  Thanks, Shannon.  I think I get it.  🙂

  Just out of curiosity, is this new?  Or is it something that just became an issue because of trying to run the two different generations of sensor that way?  It was working fine with the two Gen1 sensors written as it is.  I suppose I’m trying to figure out if I just got lucky originally.

  From the sketch, it looks like you’re trying to operate both sensors on the same logger by using a separate data pins for each sensors?  That’s not the correct way to do it because of how the underlying EnviroDIY SDI12 library functions. You should instead put both sensors on the same data line (usually D7).  Each sensor will need its own unique a…[Read more]

  Hey all.

  I have a station that started out with two Gen1 METER Hydros 21s and has transitioned to having one  Gen1 and one Gen2.  Unfortunately, I can’t seem to get the sketch to work now even though it was before.  It compiles and uploads to the card, and the Gen1 sensor does just fine but I get -9999 from the Gen2 now that it’s installed.  Whe…[Read more]

  Shannon Hicks replied to the topic Turbidity Sensor Information/Questions in the forum Environmental Sensors 2 years, 1 months ago

  The old Campbell OBS3 turbidity sensor was an analog-output sensor that had 2 separate voltage outputs, one 5v power supply wire, and 3 ground wires, which is why I designed the old version of the 6-pin screw terminal board that way, because we primarily used it with the OBS3 sensors and connected it to one of the Aux Analog Grove jacks on the…[Read more]

  Hi Neil! Jumping in here to explain as site admin to explain about link limits. You’re correct: a common characteristic of comment spam is a large number of hyperlinks. That said, you should be able to post up to 15 links before your post is held for moderation. If you’re finding that’s not the case, please email webmaster@stroudcenter.org so that…[Read more]
