Note 1  Given the nature of the sensor design and sensor operating frequency, the system has inherent susceptibilities 

to Radio Frequency signals. The repeatability specification when subjected to certain RFI environments, such 

as those outlined in IEC 61000-4-3 and IEC 61000-4-6, may be significantly reduced. 

The system level repeatability will be particularly affected when placed in an electric field of 3 V/m or greater 

in the 150 KHz to 1000 MHz range. RFI mitigation practices and physical deployment changes may reduce the 

system susceptibility. If deployments are planned in high RFI energy environments, Onset recommends on-site 

testing to determine system level repeatability.

 

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

). 

Solar Panel:

 Position the solar panel towards the sun to charge 

the mote batteries (see 

Deploying and Mounting

). 

Sensor Cable:

 This is the cable that connects the mote to the 

sensor. 

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 HOBOnet Wireless Sensor 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.

 

Solar Panel Cable:

 This cable connects the built-in solar panel 

to the mote circuitry. 

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 HOBOnet 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.
