SIM Size & Access Internal Micro 3FF SIM

 

ONBOARD DESIGN AND MECHANICS

Operating Temperature -30°C to +60°C
LiPo Charger – At < -10°C and > +45°C the internal backup battery will not be charged as a safety precaution due to the dangers associated with charging batteries at extreme temperatures.
Self-Resetting Fuse Built-in self-resetting fuse makes installation simple and safe
Cellular Antenna Internal. Supports optional external antenna for maximum range.
GPS Antenna Internal
LiPo Battery Charger Internal
3-Axis Accelerometer 3-Axis Accelerometer to detect tampering (planned in future firmware release)
Diagnostic LED 2 Diagnostic LEDs and Push Button for testing and operational status
Flash Memory Store months of records if device is out of cellular coverage
Onboard Temperature The device reports internal temperature and prevents the internal battery from charging in extreme temperatures.
Internal temperature provides an indication of ambient temperature but may not always be precise. Use an external sensor for precise temperature monitoring.

 

ONBOARD LOCATION

Module Nordic nRF9160 internal GPS
Constellation GPS
*Location Accuracy ~3m CEP, 50%, GPS, Open sky
GNSS Assistance GPS predicted ephemeris data for greater sensitivity and position accuracy
Low Noise Amplifier GPS signals are boosted by a low-noise amplifier (LNA) allowing operation in low signal

*Positioning accuracy specifications are provided by the GNSS supplier and reflect ideal conditions. Device configuration, installation, environmental conditions, augmentation services, and many other factors may lead to variations in positioning accuracy.

 

ONBOARD INTERFACES

Digital Inputs 1 x Digital Input with configurable pull up/pull down
0-40V DC input range
On/Off thresholds: On >2V, Off <1V
Can be used for pulse counting (max 40Hz)
Plugin Board The versatile and flexible Hawk architecture caters for plug-in cards that define the 9 inputs/outputs, offering limitless options for interfacing to sensors. Flexible onboard output power to power your sensors. See the current card list below or contact us to discuss your requirements.

 

 

ONBOARD SMARTS

Auto-APN Auto-APN allows the device to analyze the SIM card and select the correct APN details from a list that is pre-loaded in the device’s firmware
Voltage Monitoring LiPo battery and external voltage readings for “Battery Low” and “Power Loss” alerts
Task Management Powerful onboard task management allows you to schedule tasks or run tasks based on sensor thresholds and events, even when out of cellular coverage
