This sensor is a carrier/breakout board for ST's VL53L0X laser-ranging sensor, which measures the range to a target object up to 2 m away. The VL53L0X uses time-of-flight measurements of infrared pulses for ranging, allowing it to give accurate results independent of the target's colour and surface. Distance measurements can be read through a digital I²C interface. The board has a 2.8 V linear regulator and integrated level-shifters that allow it to work over an input voltage range of 2.6 V to 5.5 V, and the 0."³ pin spacing makes it easy to use with standard solderless breadboards and 0."³ perfboards.

The VL53L0 uses ST's FlightSense technology to precisely measure how long it takes for emitted pulses of infrared laser light to reach the nearest object and be reflected back to a detector, so it can be considered a tiny, self-contained lidar system. This time-of-flight (TOF) measurement enables it to accurately determine the absolute distance to a target without the object's reflectance greatly influencing the measurement. The sensor can report distances of up to 2 m (6.6 ft) with 1 mm resolution, but its effective range and accuracy (noise) depend heavily on ambient conditions and target characteristics like reflectance and size, as well as the sensor configuration. (The sensor's accuracy is specified to range from ±3% at best to over ±10% in less optimal conditions.)

Ranging measurements are available through the sensor's I²C (TWI) interface, which is also used to configure sensor settings, and the sensor provides two additional pins: a shutdown input and an interrupt output.

The VL53L0X is a great IC, but its small, leadless, LGA package makes it difficult for the typical student or hobbyist to use. It also operates at a recommended voltage of 2.8 V, which can make interfacing difficult for microcontrollers operating at 3.3 V or 5 V. The breakout board addresses these issues, making it easier to get started using the sensor, while keeping the overall size as small as possible.

The carrier board includes a low-dropout linear voltage regulator that provides the 2.8 V required by the VL53L0X, which allows the sensor to be powered from a 2.6 V to 5.5 V supply. The regulator output is available on the VDD pin and can supply almost 150 mA to external devices. The breakout board also includes a circuit that shifts the I²C clock and data lines to the same logic voltage level as the supplied VIN, making it simple to interface the board with 3.3 V or 5 V systems, and the board's 0."³ pin spacing makes it easy to use with standard solderless breadboards and 0."³ perfboards.

Note:The VL53L0X from ST Microelectronics is a time-of-flight ranging system integrated into a compact module. This board is a carrier for the VL53L0X, so we recommend careful reading of the VL53L0X datasheet before using this product.

Lidar time of flights sensors

This is a very good item that arrived just righ for a prject I am working on. I built 11 of these into a bar suspended over a conveyor which I want to see the level of material Running down the conveyor over time. The library is quite complex but you don't need to get into it, although it is only in C++. I tried converting it to C# for use on a Rasberry PI running WIN10 IOT core, but in the end did the heavy lifting for the I2C using an Arduino Nano and passed serial data to the PI using a bespoke Synchronous serial interface I wrote, as the PI's serial interface is awful. The PI will post web requests up to a web server showing graphs of the material on the conveyors.

Great piece of kit

This does exactly as is says on the box, connect to your arduino and immediately see accurate distance measurements in mm, There is some fluctuating of the readings (interference) which I have not found a cure for, but it is exactly what I needed to control the height of a SWATH boat above the water, and there is no other sensor which will do that.
