Sensor States | Ouster Sensor Docs

On power-up, the sensor starts in the initialization phase. The state machine below shows the primary operating states and the common transitions between them. The firmware update state is isolated and independent. It can be triggered from any operating state and results in a reinitialization of the sensor only upon a successful update.

Operating State	Description
WARMUP	Sensor self-heats when low temperature is detected before returning to initialization.
INITIALIZING	Sensor boot, checks, configuration application, and recovery from non-fatal conditions.
ERROR	Latched fatal failure state. Motor and laser output are disabled until the fault is cleared and the sensor is reinitialized.
RUNNING	Sensor has completed initialization and is producing normal output.
STANDBY	Low-power mode with motor and laser output disabled while the sensor remains responsive.
UPDATING	Sensor is applying a firmware update and will reboot automatically when complete.
