  Unfortunately no other turbidity sensor, just using distilled water.

  Emailed you the current code.

  Thanks!

  It’s probably easiest if you email me your code so I can check it.  We used 8 of those sensors for 2 years in a continuous deployment and didn’t have any drift or loss of calibration, so I don’t think there’s anything else you need to do with it.  If you’ve got another type of calibrated turbidity sensor or a turbidity standard, you could do a c…[Read more]

  Does the 511-a lose cal over time?  Is it confused because we had it un-powered for over a year?

  I’m waiting for a USB to RS485 adapter to try to use the smartpc utility to see if calibrating the unit will do anything, as well as see if the units are working correctly.

   

  Thanks.

  Thanks Shannon,

  I used mostly the same code but replaced the GUIDS and inserted into the originally working code for one of our current stations.

  I initially tried with 0x01, and just tested again with 0x01.  The wiper wipes 3 times and stops.

  Readings for temp and turbidity are still -9999.0 and -9999.0.

  Thanks.

  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 sent you some code last year that should work with the Y511-A.  I can’t tell what other changes you’ve made to the code, but in snippet you posted above, the address should be 0x01 on line 7, not 0x02.

  Also tried with another Yosemitech 511-a, same behavior so don’t think it’s an

  issue with the sensor.

  Hey,

  Using the Yosemitech 511-a, with the regular code[snippet below], on a ver 1.1 mayfly, using the older modbus wing.

  I get

  YosemitechY511 at modbus_0x02 reports temperature is -9999.0 degreeCelsius
  YosemitechY511 at modbus_0x02 reports turbidity is -9999.00 nephelometricTurbidityUnit

  The sensor turns on, wipes back and forth 3 times, I…[Read more]

  Braedon replied to the topic Controlling 12-volt heaters with a power relay in the forum Infrastructure and Equipment 1 months, 1 weeks ago

  @shicks I wanted to run by what my thought process is with these relays and some of the questions I have now that I have purchased a few. I think my questions are general enough that you should be able to help me with them. I am looking to connect the Seeed relay to the D10-D11 grove terminal on the Mayfly. This would connect the relay’s SIG pin…[Read more]

  Cal started the topic System Hangs with Hologram Outage in the forum Mayfly Data Logger 1 months, 1 weeks ago

  During the Hologram outage last week, 12 of my old stations in the field (all Mayfly 0.5 and Digi modems) stopped reporting measurements over the Internet.  Then when Hologram fixed the problem, 10 of these stations (which have been running since 2020), came back online and reported all their measurements including the time Hologram was down.…[Read more]
