Shannon Hicks replied to the topic Pelican 1120 drilling template in the forum Mayfly Data Logger 4 minutes ago
I haven’t seen any other templates besides the one you linked. I never use them myself, I just lay them out in whatever pattern is the easiest, based on the sizes of the cable glands. I prefer to stagger them as shown in this photo from the kit’s shop page, since that makes it easier to get your hand around the end part to tighten them. I us…[Read more]

Can someone direct me to a 4 hole drilling template if it exist?
I found this: https://github.com/EnviroDIY/EnviroDIY_Mayfly_Logger/blob/master/hardware/1120Pelican_enviroDIY_5.pdf
I thought I found and bookmarked a 3 hole version before, but now I can’t seem to locate it.
Thank You

Are you referring to an EnviroDIY Monitoring Station kit which contains a Mayfly Data Logger, or is your station based on some other type of controller? And are talking about limiting the amount of current your monitoring kit could draw from a power source, or are you talking about limiting the output current of the kit in regards to the load…[Read more]

We are looking at adding an external circuit breaker to protect a monitoring kit. We are configuring a monitoring kit to be a mobile or portable unit, that can be carried aboard a ship/boat of opportunity. Often in the field on a boat or in some weather, equipment gets wet.
What level of current should an external breaker be rated to prevent…[Read more]

A few of the folders in “ModularSensors_Dependencies_v.0.35.0.zip” are named with blank spaces or with longer names, if you go into any of the folders with spaces, copy the name of the .h file and rename the folder to that name, it works.

Hi Shannon,
Thanks for the quick reply. Since we’re installing these stations right at the edge of the salt marsh/forest, I think we’ll have sufficient light to power the modem + Hydros 21.
Appreciate it,
Elliot

There’s nothing electrically wrong with having all 4 resistors populated on that board, but only one pair will be used for your sensor analog input, and the other pair will not be connected to anything and will therefore not be performing any function.

Since I am only using one C-FLOUR sensor, does having two pair of soldered resistors affect anything or should I redo the screw terminal board to only have one pair of resistors?
Thank you for the tip on needing two separate screw terminal boards because each C-FLOUR needing 2 ground terminals each.
Shannon Hicks replied to the topic Continous HAB monitoring in the forum Mayfly Data Logger 1 weeks, 2 days ago
If you only have one C-FLUOR sensor, then you only need one pair of resistors, since there’s only one analog signal from the sensor. There ARE two ground wires, which is why I asked how many sensors you were using with this one screw terminal board. In order to connect two Turner analog sensors to a Mayfly Logger, it’s good to use 2 separate s…[Read more]
