# The ambient light sensor lacks a lens structure ## Problem environment The ambient light sensor (ALS) would benefit from a surrounding structure to block unwanted peripheral illumination. ## Steps to reproduce 1. Refer to the layout and find Q1 1. Observe peripheral light sources ## Expected result The ambient light sensor lacks a lens structure. ## Actual result No lens structure surrounds the ALS. ## Resources A FDM or SLA 3D printer can be used to manufacture a simple hollow box. A CO₂ laser can be used to cut the lens and all pieces can be glued together onto the PCB. ## Severity level This is **low priority** because project requirements do not specify any sensor logic.
