Fiona started the topic Add Variable for Atlas Sci Sensor in the forum Environmental Sensors 2 years ago
Hello,
Is it possible to add specific conductance as a variable for the Atlas Scientific conductivity sensor in Monitor My Watershed?
Thanks in advance,
Fiona

Just an FYI I’ve just picked up that some of my sensor have lost data on or about Aug 6 1pm PST for 5 horus.
I’ve made great efforts to track the delivery of measurements, I’m thinking its MMW that has swallowed the data.

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 2 years, 1 month 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 2 years, 1 month 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 2 years, 1 month 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]
Stephen H replied to the topic Yosemitech 511-a no readings? in the forum Environmental Sensors 2 years, 1 month ago
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 2 years, 1 month 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.
