1 INTRODUCTION
1.1 PURPOSE
Thank you for purchasing the Uranus Meteo Sensor. This pocket-sized device is an
all-around astronomer, astro-imager companion.Smaller than the size of a cigarette
box, and equipped with a variety of digital sensors, can precisely report the ambient
temperature, humidity, pressure, cloud height, cloud coverage, astronomical dawn,
twilight time, and the night sky brightness.
1.2 DEVICE CARE
The device electronics are housed inside an aluminium anodized blue enclosure.
The enclosure is made from aircraft aluminium alloy 6061 which provides very good
corrosion resistance. The label button on top of the device is water-resistant and the
material was selected to last a long time. However, the device is not waterproof and
it should not be installed outside for long term, exposed to weather conditions e.g.
direct sunlight, rain, snow.
A black silicone case protects the device from drops and scratches. Also it does not
allow contact of aluminium enclosure with your palm. (especially during cold nights
the heat transfer from your hand to the metal can be really disturbing)
We strongly suggest keeping this case, especially if you plan to use the device as a
mobile unit (have it in your pocket etc). In case you need to place the device inside
your observatory, you can remove the silicon case and use the screws at the bottom
of the device to securely attach Uranus on a plate (2xM3 screws) or a tripod ball
head ( 3/8-16 UNC thread).
Please note that the device is not water-sealed and you should not leave it
exposed to weather conditions such as rain or snow. However, the device can
be placed into a roll-off observatory to measure night conditions, for
astronomical observations, when the roof is open.
