Atlas Tear-Down Photos
« on: October 08, 2018, 03:17:59 AM »
I'm taking apart my beta Atlas.  Here's what I have so far.  Note that production models could be different.

This is the bottom piece of the pagoda.  You can remove it with no tools.

After removing the pagoda bottom, you can reach the temp/humidity module.  It can also be removed with no tools.

Note the slots in the "cage" that houses the SHT31 chip.  It has a fine mesh screen, apparently to keep out critters.

I imagine this is how Acurite would offer a replacement module.  I could get down to the actual chip by removing some small screws, but that seems to defeat the purpose of tool-free installation.

This is the pagoda middle.  It's all held together by three long screws.

This is the top tier of the pagoda, holding the aspiration fan (view from bottom).

This is also the top tier of the pagoda, but a view from the top.  Note the little plastic cap covering the motor.

With the plastic cap removed you see the top of the motor.

 [ You are not allowed to view attachments ]


Here is a close-up of the motor top.  Note the black material.  Initially I thought this was some sort of sticker I could peel off, but it seems to be some sort of soft potting-like material.  You can see some scrapes my screwdriver made when trying to peel it off.

The motor doesn't seem removable and is permanently mounted in the pagoda top.  Also, the wires don't have a plug in this section.  That makes this section hard to remove.  There is a plug to the main board, but the wires are still routed in such a way to make things difficult.

In short, this makes it really hard to replace the motor section.  A motor plug in the pagoda bay would make it feasible, though, but I wonder why they didn't do that like everything else.  Perhaps that's just because this is a beta unit?

This is the battery bay with the 4 little screws removed.  Note the red lightning sensor module is installed.

This is the flip-side of the battery bay module.  Note all the wiring nicely labeled.  Marking of the receptacles is embossed in the plastic for easy identification.

Obviously the main board must be between the battery bay and this level.  I'll need to remove some more screws to show it (haven't done that yet).

Note the vertical plastic portion... that's probably to cover the antenna.

The conformal coating on the boards looks decent.  Is there any silicone grease on the connectors?

None that I can tell.  The connectors still work smoothly after a year or so of weather exposure, though.

Underside of rain bucket assembly.  This houses the 3 solar panels and the UV/Light intensity sensor.

This is the wind section removed from the main body.  Note that I've already removed the bottom cap which is setting to the side.

This is the bottom of the wind section with the bottom cap removed (also a few screws).  I assume this chip is what is measuring wind direction.  The thing jutting out of the bottom is the attachment cable.  I think it's a mini-USB connector if I have the names straight.  There's a "hood" over the end of the USB connector which makes it a bit difficult to see.

This is another view of the wind section with the tip of the wind vane removed.

I'm still trying to figure out if the wind section can be disassembled further without risking breakage, but I saw a screw just under end of the vane.

Removing the screw removed the wind vane tip.  Apparently this is just to cover some extra weights that were added.  I guess this improves dampening so it doesn't "flutter" as easily as the 5n1.

It didn't help in my disassembly quest, though.

This photo is lookup up under the "flare" under the anemometer section.  You can see two magnets that are being sensed to gauge how fast the cups are turning.

The tipping bucket mechanism.  Note the two calibration screws in the bottom half, and the covered reed switch in the top half.

The tipping buckets are easily accessed by lifting up the rain bucket for easy cleaning (which I've obviously never done).

Back to the temp/humidity module.

The basket covering the actual sensor removes with two screws.  You can now see the SHT31 circuit board clipped in between two plastic prongs.

Maybe if it is detecting every light ting, as opposed to only heavy lightning strikes, it explains why some are reporting such high readings.

Thanks, I just opened the snap out cage and the flip up rain bucket assembly to deal with a stuck fan and the u/v sensor not reading suddenly. Fan cage was out of alignment and one of the pins for the solar panels and the u/v sensor wasn't all the way in the plug. Got both working and it looks pretty similar to your unit. Very useful shots for anyone needing to swap out parts eventually or troubleshoot issues with out breaking things  UU
