The `bh1750` sensor platform allows you to read the ambient light level in lux from a [BH1750FVI sensor](http://cpre.kmutnb.ac.th/esl/learning/bh1750-light-sensor/bh1750fvi-e_datasheet.pdf) connected via [I2c](https://en.wikipedia.org/wiki/I²C) bus (SDA, SCL pins) to your [Raspberry Pi](https://www.raspberrypi.org/). It allows you to use all the resolution modes of the sensor described in its datasheet.
