  Thanks, Brian. What I’m really looking for is the Mayfly sketch, one specifically for an SDI 12 interface.

  Stephen H started the topic Yosemitech 511-a starting up twice? in the forum Environmental Sensors 3 months ago

  Using just the Yosemitech 511a, when it starts up it wipes 3 full times then does a reading.  When I add the code for the Hydros CTD sensor, it seems that the 511a starts up twice and wipes a full 6 times?

  Is this because the sensorPowerPin is the same for the CTD sensor and for the 511a?  Or is my setup configuration incorrect?

  Also anyone k…[Read more]

  Thank you Shannon!  Really appreciate you looking and finding the problem

  in my code.  Works now!

  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.
