The DIS Hallowell C-V2.0 is designed to operate primarily in a deep sleep mode to conserve battery life. It wakes up from this sleep state for several reasons, ensuring efficient tracking and reporting:

The Hallowell C-V2.0 reports at regular intervals known as the “heartbeat interval.” This interval is configurable, allowing you to set how often the device sends status updates to the server. It ensures you receive periodic updates on the device’s status.

If the tamper sensor is active, the device wakes up to report this event. Tampering could involve unauthorized access or removal of the device from its mounted position. Reporting tamper events helps in enhancing the security of your assets.

The Hallowell C-V2.0 also wakes up when it detects movement. The definition of movement is highly configurable and can be adjusted based on parameters such as G-force, the number of movement samples, and movement time. This flexibility allows you to tailor the device’s behavior to specific tracking scenarios.

Conversely, the device reports when it stops moving. Similar to movement detection, the definition of a stop movement event is configurable, typically based on a specified period of no movement. This feature is useful for tracking assets that should remain stationary and alerting you if they are moved.
