@ -44,6 +44,28 @@ Configuration variables:
- **update_interval** (*Optional*, :ref:`config-time`): The interval to check the
sensor. Defaults to ``60s``. It is recommended that the update interval is at least 1 second since updates can take up to 800ms when using a high resolution value.
Granular control over gain and resolution
.........................................
By default, the ``gain`` and ``resolution`` parameters set same values for both ALS and UV measurements. In real life scenarios there might be significant
differences in the light intensity and UV index, so it is recommended to use different gain and resolution values for ALS and for UV sensor to avoid saturation.
See the example below, where the gain and resolution are set to different values for ALS and UV sensors.:
.. code-block:: yaml
sensor:
- platform: ltr390
uv:
name: "UV Sensor Counts"
ambient_light:
name: "Light Sensor Counts"
gain:
ambient_light: X9
uv: X3
resolution:
ambient_light: 18
uv: 13
