Fiona started the topic Atlas Scientific Returning -9999 Values After One Good Reading in the forum Environmental Sensors 2 years ago
Hi All,
I’ve seen this discussed on the forums before but it doesn’t seem to have been solved. I have a recurring issue with the Atlas Scientific combination industrial pH/temperature sensor where it returns one good temperature value and then all subsequent values return as -9999. It will always return one good reading on startup. The other…[Read more]
Braedon replied to the topic Controlling 12-volt heaters with a power relay in the forum Infrastructure and Equipment 2 years ago
@shicks I’m also going to be adding an air temperature sensor that has a 12-volt fan in the radiation shield. The fan can run at lower power by using pulse width modulation. I’m wondering if there might be a way to accomplish this with the power relay, since the fan will have to be connected directly to the battery like the heaters on my other…[Read more]
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,

neilh20 started the topic Missing data on MMW in the forum Monitor My Watershed 2 years ago
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]
