VL53L0X TOF laser ranging sensor module

The VL53L0X (HCMODU0127) is a new generation Time-of-Flight (ToF) laser-ranging module housed in the smallest package on the market today, providing accurate distance measurement whatever the target reflectances, unlike conventional technologies. It can measure absolute distances up to 2m, setting a new benchmark in ranging performance levels, opening the door to various new applications. The VL53L0X integrates a leading-edge SPAD array (Single Photon Avalanche Diodes) and embeds ST’s second generation FlightSenseTM patented technology. The VL53L0X’s 940nm VCSEL emitter (Vertical Cavity Surface-Emitting Laser), is totally invisible to the human eye, coupled with internal physical infrared filters, it enables longer ranging distance, higher immunity to ambient light and better robustness to cover-glass optical cross-talk.

Specification:

Product code: HCMODU0127
Supply Voltage: 2.6V to 5.5V
Average active ranging sensor current: 19mA
Interface: I2C
Dimension: 13mm x 11mm


Max ranging distance



Note (1): using long range API profile

Note (2):
– Indoor: no infrared
– Outdoor overcast corresponds to a parasitic noise of 10kcps/SPAD for VL53L0X module. For reference, this corresponds to a 1.2W/m² at 940nm, and is equivalent to 5kLux daylight, while ranging on a grey 17% chart at 40cm Measurement conditions:
– Targets reflectance used : Grey (17%), White (88%)
– Nominal Voltage (2.8V) and Temperature (23degreesC)
– All distances are for a complete Field of View covered (FOV = 25degrees)
– 33ms timing budget 
All distances mentioned are guaranteed for a minimum detection rate of 94% (up to 100%). Detection rate is the worst case percentage of measurements that will return a valid measurement when target is detected.


Ranging accuracy



Measurement conditions:
– Targets reflectance used: Grey (17%), White (88%)
– Offset correction done at 10cm from sensor.
– Indoor: no Infrared / Outdoor: eq. 5kLux equivalent sunlight (10kcps/SPAD)
– Nominal Voltage (2v8) and Temperature (23degreesC)
– All distances are for a complete Field of View covered (FOV = 25degrees)
– Detection rate is considered at 94% minimum
