pub const SLOPE_MLUX_NUM: u32 = 20_636;Expand description
Millilux per count above DARK_OFFSET_RAW, as the fraction
SLOPE_MLUX_NUM / SLOPE_MLUX_DEN — 20.636 mlux per count.
Fitted through the origin from the 185 lux point:
185000 / 8965.086 = 20.636.
A fraction rather than a whole number of millilux because rounding the
slope to an integer would discard a percent or two of the answer —
more than the sub-count resolution the sampling in [crate::power]
exists to buy.
