Droplet V2 - Datasheet - Nube iO | 1
Droplet Gen2 by Nube iO is the next evolution of
our industry-leading wireless LoRa® IoT sensor,
engineered to capture accurate Temperature
and Humidity data with greater reliability and
performance than previous generations.
Designed as a surface-mount, fully wireless
device, Droplet Gen2 eliminates the need for
physical sensor wiring, significantly reducing
installation time, labour costs, and disruption for
building occupants.
Built on our enhanced Gen2 architecture, the
Droplet leverages LoRa® technology to deliver a
robust transmission range, energy efficiency,
and minimal susceptibility to object interference
compared to other wireless technologies. These
advancements make Droplet Gen2 an ideal
choice for monitoring, controlling, and
optimising various spaces.

FCC Caution.
This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions:
(1) This device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may cause
undesired operation.
Any Changes or modifications not expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment.
Note: This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates
uses and can radiate radio frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which can be determined by turning
the equipment off and on, the user is encouraged to try to correct the interference by one or
more of the following measures:
-Reorient or relocate the receiving antenna.
-Increase the separation between the equipment and receiver.
-Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
-Consult the dealer or an experienced radio/TV technician for help.
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with minimum distance 20 cm
between the radiator & your body.
