Introduction: How to Wire the VL53L1X Long-Range Proximity Sensor
The VL53L1X sensor is a long-range proximity and ranging sensing that base on TOF (Time-of-Flight) unlike IR (Infrared) sensor which measures only signal strength and can be affected by the object reflectivity, compare to VL53L1X its measures directly to a distance base on the time for emitted photons to be reflected, enabling an accurate distance ranging regardless of the object surface characteristics. This device is packed in an All-in-one miniature module which contains the laser driver and emitter as well as the single-photon avalanche diode or (SPAD) light receiver that gives the sensor their ranging speed and reliability at low power consumption.

This statement isn't correct: "measures directly to a distance base on the time for emitted photons to be reflected". It's fine to speak of photons being involved with emission, but emission does not mean that photons travel or that they are then reflected. Common misunderstanding. Instead, photons should be considered to be the energy "buckets" related to emission and absorption of E&M energy transmission. There is not a single observation ever that has required emission to result in a traveling photon, nor absorption to be the result of a traveling photon. E&M is traveling energy. It is emitted or absorbed in chunks. No need whatsoever to speak of E&M as traveling in chunks. No need to think of a photon as something that exists at all except for when the interaction occurs.
