Mote Components and Operation
Sensor Mote Closed, Front
Sensor Mote Closed, Back
Sensor Mote Opened
Mounting Tab:
Use the tabs at the top and bottom of the mote
to mount it (see
Deploying and Mounting
).
Sensor:
This is the temperature/RH sensor connected to the
mote.
Eyelet:
Use this eyelet to attach a 3/16 inch padlock to the
mote for security.
Latch:
Use the two latches to open and close the mote door.
Ground Wire Port:
Use this port to connect a ground wire (see
Deploying and Mounting
).
Antenna:
This is the built-in antenna for the radio
communications across the wireless network.
LEDs:
There are two LEDs to the left of the LCD screen. The
green LED blinks during the process of joining a network,
blinking quickly while the mote searches for a network and
then slowly as the mote registers with the network. Once the
network registration process is complete, the blue LED blinks at
4 seconds to indicate normal operation. If the mote is not
currently part of a network, the blue LED will be off. If the blue
LED is on and not blinking, there is a problem with the mote.
Contact Onset Technical Support.
Battery Holder:
The location where the batteries are installed
as shown (see
Battery Information
).
USB Port:
Use this port to connect to the mote to a computer
via USB cable if you need to update the firmware (see
Updating
Mote Firmware
).
Button:
Push this button for 1 second to illuminate the LCD or 3
seconds for the mote to search for a wireless sensor network to
join (see
Adding the Mote to the HOBOnet Wireless Sensor
Network
).
LCD Screen:
The mote is equipped with an LCD screen that
displays details about the current status. This example shows all
symbols illuminated on the LCD screen followed by definitions
of each symbol in the table.
LCD Symbol Description
The battery indicator shows the approximate battery
charge remaining.
This is a signal strength indicator. The more bars, the
stronger the signal between motes. If there is no x
icon next to the signal strength indicator, then the
mote is part of a HOBOnet Wireless Sensor Network.
An empty signal strength icon plus the x icon
indicates that the mote is not currently part of a
network. See
Adding the Mote to the HOBOnet
Wireless Sensor Network
for details on how to add a
mote to the network.
When the mote is in the process of joining a
network, the signal strength icon will blink and then
the bars in the icon will cycle from left to right. The x
icon will blink during the last step in the network
registration process (see
Adding the Mote to the
HOBOnet Wireless Sensor
Network for details).
This indicates a problem with the sensor itself (the
mote is operational). Check the sensor and make any
adjustments to it as needed. Contact Onset
Technical Support if the problem persists.
Adding the Mote to the HOBOnet Wireless
Sensor Network
The mote must join a HOBOnet Wireless Sensor Network
before it can begin measuring temperature and RH and
transmitting data. This requires accessing the station and the
mote at the same time so it is recommended that you complete
these steps before deploying the mote.
