Thanks @shicks. COVID has meant that not everything is available at my end of the world, so I need to compromise sometimes!

Shannon Hicks replied to the topic Solar Panels for Mayfly in the forum Infrastructure and Equipment 1 day ago

That panel wouldn’t be a problem. Any panel that produces 6v will be safe for the Mayfly, but some cheap 6v panels actually produce higher than 6v in direct sun, so you should measure it (under load) in full sun to make sure it won’t output higher than the max input voltage of the MCP73831 (7 volts). The solar charger on the Mayfly boards v…[Read more]

Hi,

This might be a stupid question but what solar panels are compatible with the Mayfly? I understand it takes up to 6V input, but am I constrained by wattage as well? Would I risk damaging the system if I installed a 6V 6W panel like…[Read more]

Matt Barney replied to the topic Hydros-21 Depth Temp Compensation in the forum Environmental Sensors 1 day, 3 hours ago

Hi Dan,

I’m curious whether it’s possible to identify Gen 1 vs Gen 2 Hydros21; are they labeled? I’m wondering what I’ve got.

Thanks,

Matt

Thanks @neilh20. I will definitely be interested in these when they are available.

@aufdenkampe do you have any feedback about YOSEMITECH turbidity sensors? My questions are:

1) Are they as reliable as other turbidity sensors, i.e. do they drift more readily, or provide strange values? For $510USD (non-wiper) or $680USD (wiper), they seem…[Read more]

Shannon Hicks replied to the topic Com Ports not connecting to logger in the forum Mayfly Data Logger 1 day, 5 hours ago

Are you using Windows or Mac for connecting to the Mayfly board? Have you tried more than one USB cable? Are these two unresponsive Mayfly boards brand new or are they running previously-programmed sketches? Are there any LEDs that light up when you power the Mayfly board, either from a USB cable or a LiPo battery pack? Is the small slide swi…[Read more]

I wonder if anybody has been thinking/trying low cost cameras as a sensor.?

Danielle IWI replied to the topic Com Ports not connecting to logger in the forum Mayfly Data Logger 1 day, 6 hours ago

I did forget that there should be a new port number to the logger, but, yes, it is not assigning a COM port number for two of our loggers. Is there any reason why some loggers would be able to be assigned a port while others would not?

Hi Scott, I look forward to seeing your test results. Meter Group exchanged my Gen 1 Hydros21 with a brand new Gen2. I am programming it right now and will post new results after I test it. We are gearing up to expand our Mayfly network and I want to make sure we are using a dependable sensor before we purchase several units.

I’ve been working on a next revision board. Details at https://github.com/neilh10/SensorModbusMaster/tree/release1/hardware/knh002-MayflyWingShield

overview at https://github.com/neilh10/SensorModbusMaster/tree/release1/hardware

I don’t have any time frame on availability due to the world wide shortage of parts, but probably third quarter this…[Read more]
