|
|
===========================
|
|
|
|
.. warning::
|
|
|
|
This sensor is experimental has not been fully tested yet as I do not own all sensors. If you
|
|
can verify it works (or if it doesn't), please notify me on discord.
|
|
|
|
The ``bh1750`` sensor platform allows you to use your BH1750
|
|
(`datasheet <http://www.mouser.com/ds/2/348/bh1750fvi-e-186247.pdf>`__, `Aliexpress`_, `mklec`_)
|
|
ambient light sensor with esphomelib. The `I²C
|
|
bus </esphomeyaml/components/i2c.html>`__ is required to be set up in
|
|
your configuration for this sensor to work.
