PUTTING THE CASE THROUGH It's Paces.

  • I placed the components into the the1554H2GYCL Case as described in this photo.
    I know it's not very clean, and I plan to mount the electronics after the challenge.

Ingress Protection Rating

  • The 1554H2GYCL enclosure
    • is a Plastic Enclosure, Watertight, Polycarbonate, has a rating of IP68
    • Ingress Protection Rating: IP68 is as follows. 
    • imageimage
    • It has the highest IP rating for water and can be completely submerged in water 
    • It has the same dust rating as the other enclosure and will not let dust particles in
    • It is constructed of Polycarbonate with a Gasketed lid with two piece “tongue & groove” construction

  • I put the MKR1 design into the Case, and placed the case into the following environments.

In the Freezer

  • I placed the case in our Freezer with the other frozen foods. The results are displayed in this section.
  • The inside case temperature was brought down below Zero Fahrenheit.
  • I'm not quit sure if I'm using the Dust sensor correctly, because there were some Hight Dust concentrations in the Case.
  • image   image  image  image

In the Garage

  • I placed the Enclosure in the Garage
  • It was in the garage for about 8 hours.
  • The temperature stayed around 52F degrees inside the enclosure. you can observe the dip in the temp chart on the dashboard below. It was a bit colder outside of the garage.
  • The results are displayed in the following section.

  • image   image   image

In the SNOW

  • I placed the Enclosure in a snow bank in the back of my home.
  • It was raining and the fog was melting some of the snowfall we received last weekend.
  • I kept the snow overnight. The case was in snow for more than 24 hours. The electronics stay DRY and the Temperature stayed around 32F degrees. 
  • The results are shown in the following section.

 Put the Case in 
The SNOWSunglasses

This was placed in the
snow at about 12:00PM
during the day and conditions 
were Foggy and raining.

At 5 PM I took another Pic

I checked the vital signs
again using:

Well is 12 PM the next day
Time to dig out the Case
from the snow.

It's still running and
the Picture shows the
LCD reporting 33F degrees.
And it's still DRY inside the case.

Next some vital signs.....

In Water

  • After taking the enclosure out of the snow from the above test, I emerged it in a bucket of water, located next to the snow bank. 
  • The case was held down by a brick.
  • The results are shown in the following section.

I placed the case
in the water bucket
around 12 PM

At about 5PMI
checked the vital signs again using:

Weather conditions.

Still DRY in the case
alter 5 hours in the water.

The weather is tuning
f
rom rain to a wintery Mix

Still Running at 8pm 
and still DRY

The Weather is getting nasty
and It's dark outside.

Almost time to bring the case inside.

The Power USB charger LEDs, must be down to one by now.

Almost time to get it out of the water.

I Think  the power charger lost all it's juice .

Sure enough, according to the the last transmission according to The Thing variable list was 10:45 pm,  just before I went  outside and brought the bucket in

 image
Sure did Deader than a Doornail!!image

The pail that the case as in had a thin layer of ICE on the surface.
But when I removed the electronics from the kit, The battery was completely dead.
It had been in the case for the snow test the night before and had been powering the electronics
for about 34.5 hours.

image

The case did take on some water. though?
Don't under stand because the water sensor reported DRY, through the whole test?

Here is the weather conditions when I retrieved the case. No wonder there was a sheet of ice at the surface !! image

  • I'm now finished with the test of the 1554H2GYCL enclosure. It is Watertight and lives up to the 8 in the Ingress Protection Rating: IP68

    Good job. I wonder if your sensor picked up ice crystals in the freezer?

    No ice crystals from the freezer test .It actually held up really good.
    The submerged test did take on a little water, but the electronics and power charger were ok.
