Signal & Sense
Start from what must be measured. Motion, environmental, vision, proximity, current: the modality defines the physics before any part number, and each principle brings its own suppliers.

Package
Form & Interface
SMD, embedded or standalone. I2C, SPI or analog. Package and interface decide integration effort and board space, and the same die ships in five forms at five prices.
Treat the interface as a sourcing spec.

Calibration
Accuracy & Drift
Calibration is the question a sensor buyer pays to have answered. Accuracy, drift, IP rating, range: a datasheet figure is a claim, verified drift is an audit result. Sourcing is won or lost here.
