BH1750 Ambient Light Sensor
===========================
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 :ref:`I²C bus <i2c>` is required to be set up in
your configuration for this sensor to work.
