| 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 |
