|
properties:
|
|
operation-mode:
|
|
type: string
|
|
default: "auto"
|
|
enum: ["auto", "force"]
|
|
description: |
|
|
Mode of operation.
|
|
- "auto": the sensor performs sampling continuously,
|
|
- "force": the sampling is performed on every fetch command.
|
|
|
|
Defaults to sensor reset value.
|
|
|
|
measurement-period:
|
|
type: int
|
|
default: 40
|
|
enum: [10, 20, 40, 80, 160, 320]
|
|
description: |
|
|
Measurement period of the sensors in ms.
|
|
Higher values yield lower power consumption.
|
|
Note:
|
|
- [10, 80] ms only if low power mode is inactive
|
|
- [80, 320] ms only in low power mode
|
|
|
|
Defaults to 40 ms which is supported in both normal and low-power mode.
|
|
|
|
proximity-it:
|
|
type: string
|
|
default: "1"
|
|
enum: ["1", "1.5", "2", "2.5", "3", "3.5", "4", "8"]
|
|
description: |
|
|
Proximity integration time in T.
|
|
Defaults to sensor reset value.
|
|
|
|
proximity-itb:
|
|
type: int
|
|
default: 25
|
|
enum: [25, 50]
|
|
description: |
|
|
Duration of the proximity integration time T in us.
|
|
Defaults to sensor reset value.
|
|
|
|
multi-pulse:
|
|
type: int
|
|
default: 1
|
|
enum: [1, 2, 4, 8]
|
|
description: |
|
|

|
|
Higher values increase accuracy and power consumption.
|
|
Defaults to sensor reset value.
|
|
|
|
laser-current:
|
|
type: int
|
|

|
|
Activate low power mode.
|
|
This allows to increase the measurement period up to 320 ms.
|
|
|
|
high-gain:
|
|
type: boolean
|
|
description: |
|
|
Activate the high gain mode.
