Hi Fiona, @srgdamiano may be able to help you with this. There is also a pathway within the Monitor My Watershed site itself for making sensor requests. I’ll describe it here in case it is also helpful to others.

When adding a new sensor to a site on MonitorMW, if you don’t see what you need in the Add New Sensor modal window, scroll to the…[Read more]

@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]

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

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.

@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]

Setting the channel twice did the trick.

Thanks!
