+
+            This driver uses the H-Resolution Mode and the default measurement
+            time register (MTreg) of 69. According to the datasheet this is
+            the recommended mode for most applications. Typical measurement
+            time in this mode is 120ms
+
+            This driver uses the One Time Measurement feature of the BH1750. The
+            sensor returns to Power Down mode after each reading.
