VL53L0X Time of Flight Sensor

Measure distance to a target object

Since R2025a

• 

Libraries:
STM32 Microcontroller Blockset / Sensors / IMU Sensors

Description

The VL53L0X Time of Flight Sensor block measures the distance to a target object for a complete field of view (FOV = 25 degrees). This block also provides the option to select one of four ranging modes based on your requirements.

Note

XSHUT connection is required for VL53L0X sensor. Connect the XSHUT pin to vcc.

Ports

Output

Distance — Object distance

vector

The Distance port outputs the target object distance in millimeters

Data Types: uint16

Parameters

I2C module — Module for communication

0 (default)

Specify the module on the board that you are using for I2C communication.

Programmatic Use

Block Parameter: I2CModule

I2C address — I2C address of sensor

0x29 (default)

The I2C address of the VL53L0X sensor from which the block reads the values. You can configure this value. The range of I2C address is from 0x08 to 0x77.

Programmatic Use

Block Parameter: I2CAddress

Ranging Mode — Distance ranging mode of VL53L0X sensor

Default (default) | High accuracy | Long range | High speed

Select the distance ranging mode for measuring the distance to the target object. The four ranging modes available are shown in this table.

Ranging mode	Timing budget	Typical max range	Typical application
Default	30 ms	1.2 m	standard
High accuracy	200 ms	2 m	precise measurement
Long range	33 ms	1.2 m	long ranging for dark conditions
High speed	20 ms	1.2 m	high speed where accuracy is not priority

The timing budget is the time taken by the sensor to perform one range measurement.

Programmatic Use

Block Parameter: RangingMode

Sample time — Time interval to read data

-1 (default) | positive integer

Specify how often this block reads the data from the VL53L0X sensor. When you set this parameter to -1, Simulink^® determines the best sample time for the block based on the block context within the model.

Programmatic Use

Block Parameter: SampleTime
