BETAVL53L0X940 nm time-of-flight ranging sensor
Measure distance from the flight time of invisible infrared light.
VL53L0X combines a 940 nm vertical-cavity laser, a single-photon avalanche-diode receiver and ranging electronics in a 4.4 × 2.4 mm optical package. It estimates distance using time of flight, then delivers a range result and validity status over I²C. The bare sensor uses 2.6–3.5 V power. It supports 1.8 V or supply-level I/O, selected during initialization; the example uses 2.8 V with the API configured for 2V8 mode. A breakout board may add regulation or level shifting, but those are not features of the bare package. Range depends on the selected timing budget, target reflectance and ambient infrared light. The 2 m profile is intended for dark conditions, not a guaranteed distance under sunlight. Use ST’s API, calibration and cover-glass guidance, and check measurement status before accepting a reading.
