+# BH1750 usermod
+
+This usermod will read from an ambient light sensor like the BH1750 sensor.
+The luminance is displayed both in the Info section of the web UI as well as published to the `/luminance` MQTT topic if enabled.
+
+## Installation
+
+Copy the example `platformio_override.ini` to the root directory.  This file should be placed in the same directory as `platformio.ini`.
+
+### Define Your Options
+
+* `USERMOD_BH1750`                                - define this to have this user mod included wled00\usermods_list.cpp
+* `USERMOD_BH1750_MAX_MEASUREMENT_INTERVAL`       - the max number of milliseconds between measurements, defaults to 10000ms
+* `USERMOD_BH1750_MIN_MEASUREMENT_INTERVAL`       - the min number of milliseconds between measurements, defaults to 500ms
+* `USERMOD_BH1750_FIRST_MEASUREMENT_AT`           - the number of milliseconds after boot to take first measurement, defaults to 10 seconds
+* `USERMOD_BH1750_OFFSET_VALUE`                   - the offset value to report on, defaults to 1
+
+All parameters can be configured at runtime using Usermods settings page.
+
+### PlatformIO requirements
+
+If you are using `platformio_override.ini`, you should be able to refresh the task list and see your custom task, for example `env:usermod_BH1750_d1_mini`.
