Smart.Hub™ Pro, Cellular Interface
General Description
Throughput
The Smart.Hub™ Pro is a versatile and reliable IOT gateway device
for use in indoor applications. Smart.Hub™ products are gateways
used to move data from Whisker.Block® sensor blocks and end user
customized Whisker.Engine™ based sensor nodes to the
Whisker.io™ cloud platform.
The number of devices that can be supported by this hub varies with
the reporting rate of the connected devices. This is a single channel
hub, which ultimately determines its limitations; with a single
channel, this hub can process about 1,800 messages an hour. The
following table estimates device capacity for several different
update rates.

Update Rate

24 Hours
This hub supports two-way communications with field devices that
support the Whisker.io™ protocol. For battery powered devices, the
hub will queue down-stream messages (commands) and send them
to the device when it reports in at its sampling interval; therefore,
the command latency is equivalent to the update rate of the device.
For line powered devices, commands are sent immediately, with a
latency of less than 1 second.
Whisker.io Services
If the hub loses connectivity to the Internet, it will buffer all
incoming messages from field devices to storage on the SD card.
When hub connectivity is restored, the messages will be sent to the
cloud for storage and forwarding. In the event of catastrophic
failure, the data on the SD card can be recovered using our Data
Recovery App (Windows).

Devices that are configured with the storage service
will persist their historic data in the Whisker.io cloud,
making it available for visualization and analysis using
our Whisker.io™ Portal web-based software.
Rules based alerting allows a text or email to be sent
when the specified condition is met and when it
clears.
Secure, user friendly dashboard with visualization
through gauges, graphs, sensor signal strength and
fuel gauges.
The forwarding service allows two-way
communications between Whisker.io devices and
third party platforms such as Amazon, ThingLogix, etc.

Connectivity Options
Every Whisker.io™ Hub can connect to the Internet via Ethernet. Hubs that are purchased with the Cellular option can also
connect via Cellular.
Installation and Setup
All Whisker.io™ hubs are truly plug-and-play, requiring no provisioning or setup in the field. Simply mount the hub, connect it to
power, and wait for all the status lights to come on.
Once a hub is installed, it is automatically configured to work with devices within its transmission range.

Whisker.Block®, Internal Temp
General Description
Internal Channels
Whisker.Blocks® are long-range, wireless sensors that come in a
variety of I/O and power configurations. These sensor blocks use our
proprietary long range wireless communication technology, ensuring
reliable and robust operation.
They can be configured for battery or external power. When
powered from internal batteries, the sensors can operate for 10 or
more years, depending on the sensors use and configuration.
Each sensor is housed in a durable, IP67 enclosure that supports a
variety of mounting methods. External sensors are connected via
one or two 4-pin M8 style waterproof connectors, depending on
how many external channels are configured.
The long range, exceptional battery life, and flexible I/O
configurations of the Whisker.Block® make it the perfect choice for
nearly any IoT application.
This Whisker.Block® is configured with two (2) internal channels:
Battery Voltage
Ambient Temperature
External Connections
This Whisker.Block® has no configured external channels
Power
This Whisker.Block® is powered internally using a 3.7V, 5.2A-H LiThCl
battery pack that should give 10+ years of service life before a
battery change is required, assuming a 5 minute update period.
Con 2: Not used
Con 2: Not used
Range
They come in a variety of configurations with multiple external
channels for various analog and digital inputs.In an unobstructed,
outdoor line-of-site environment, the sensor should be able to
communicate for more than 0.8 kilometers assuming a receiving
antenna elevation of 3.0 meters. If the receiving antenna is raised to
6.1 meters or more, the range should increase to more than 1.6
kilometers.
When used in environments where line of sight cannot be obtained
or where there are many reflective obstacles in the transmission
path, the range will degrade due to multi-path fading. It is
impossible to predict the transmission range of a Whisker.Block® in
any specific situation, so we do encourage users to take advantage
of our site survey tools to ensure coverage exists anywhere a sensor
is to be deployed. For more information on site survey techniques,
see application note .
