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 4 months, 2 weeks 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!

Stephen H replied to the topic Yosemitech 511-a no readings? in the forum Environmental Sensors 4 months, 2 weeks ago

Unfortunately no other turbidity sensor, just using distilled water.

Emailed you the current code.

Thanks!

Shannon Hicks replied to the topic Yosemitech 511-a no readings? in the forum Environmental Sensors 4 months, 2 weeks ago

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.

Stephen H replied to the topic Yosemitech 511-a no readings? in the forum Environmental Sensors 4 months, 2 weeks ago

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.

Shannon Hicks replied to the topic Yosemitech 511-a no readings? in the forum Environmental Sensors 4 months, 2 weeks ago

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.

Stephen H replied to the topic Yosemitech 511-a no readings? in the forum Environmental Sensors 4 months, 3 weeks ago

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

issue with the sensor.

Stephen H started the topic Yosemitech 511-a no readings? in the forum Environmental Sensors 4 months, 3 weeks ago

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]

@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 4 months, 3 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]

Setting the channel twice did the trick.

Thanks!

D_Manning started the topic Sketch for rain gauges (SDI 12 interface) in the forum Environmental Sensors 4 months, 3 weeks ago

Would anyone have a Mayfly sketch for rain gauges such as METER’s ECRN-50 or -100 or Campbell’s Rainvue 10 (i.e., SDI 12 interface)? If it incorporates an Adafruit Trinket, all the better, but if it doesn’t, no problem.

Shannon Hicks replied to the topic Hydros21 sensors not returning data in the forum Mayfly Data Logger 4 months, 4 weeks ago

When you did the address changing sketch, did you get a positive result using the serial monitor that showed the channel was changed to something other than 1? Sometimes there’s a glitch where you have to set the channel twice before the change actually happens and it stays on the new channel.

What sketch are you using for the logging sketch…[Read more]

kwolfe replied to the topic Hydros21 sensors not returning data in the forum Mayfly Data Logger 4 months, 4 weeks ago

We tried that but are still getting -9999 values.

Shannon Hicks replied to the topic Hydros21 sensors not returning data in the forum Mayfly Data Logger 5 months ago

Did you do the example “b_address_change” sketch first, to change the sensor’s default channel from 0 to 1?

kwolfe started the topic Hydros21 sensors not returning data in the forum Mayfly Data Logger 5 months ago

We are unable to get our Hydros 21 CTD sensor to return data. We are getting -9999 values on both the SD card and the website. All the connections are secure. The SDI-12 address is set as follows:
<div>
<div> const char* hydrosSDI12address = “1”; // The SDI-12 Address of the Hydros 21</div>
