All three models output one distance point. Check target reflectivity, real distance, mounting environment and power first, then compare weight, power, protection and field of view; the same headline range does not imply the same result for every target or environment.
TFmini-S is about 5 g and is currently specified at 0.1–12 m with rates up to 1000 Hz and UART, I²C and I/O, fitting payload- and space-constrained single-point ranging.
Boundary: Usable range changes with target reflectivity and environment; current material does not state an enclosure protection rating, so outdoor use needs system-level protection and mounting validation.
View productTFmini Plus is also a 0.1–12 m single-point sensor; current parameters list IP65 and a 3.6° field of view. Consider it when the platform can accept about 12 g and those protection and coverage traits matter.
Boundary: A wider field of view is not scanning or multi-channel output; dark targets, strong ambient light and out-of-range readings still require validation against specified conditions.
View productTF-Luna is currently specified at 0.2–8 m, under 5 g and no more than 0.35 W, fitting short-range single-point input in a controlled mounting position.
Boundary: 3.3 V refers to the communication logic level, not the specified supply; the supply range is 3.7–5.2 V, and an unenclosed installation needs separate protection.
