VL53L0X Laser Distance Sensor

  The VL53L0X is a next-generation ToF (Time-of-Flight) laser distance sensor developed by STMicroelectronics. It utilizes the second-generation FlightSense™ technology, which operates based on the Time-of-Flight principle. By calculating the time it takes for photons to travel back and forth, the sensor can measure distances accurately. Compared to the previous generation VL6180X, the VL53L0X extends the measurement range to 2 meters, offering faster measurement speeds and higher energy efficiency. In addition, to facilitate integration, ST provides the VL53L0X software API and comprehensive technical documentation. Through the main I2C interface, the sensor outputs distance data to the application side, significantly reducing the development effort for users.

Hardware Connection

The VL53L0X module typically has four main connection ports: VCC, GND, SDA, and SCL.

• Connect VCC to the 3.3V of the development board.
• Connect GND to the GND of the development board.
• Connect SDA (Data Line) to the A4 or SDA port on the development board (SDA is pin A4).
• Connect SCL (Clock Line) to the A5 or SCL port on the development board (SCL is pin A5).

Usage Method

Install Library

In the Arduino IDE, go to Tools > Manage Libraries..., search for and install the Adafruit VL53L0X library.

Enter the code:

Usage Testing

Place an object 20 cm away from the distance sensor, then read the sensor data and output it through the serial monitor.
