VL53L0X Time-of-Flight (ToF) Laser Ranging Sensor Breakout VL53L0XV2 Laser Flight Distance Measurement Module I2C IIC for Arduino(Pack of 4)

The VL53L0 uses ST’s FlightSense technology to precisely measure how long it takes for emitted pulses of infrared laser light to succeed in the nearest object and be reflected back to a detector, so it may be thought to be a tiny, self-contained lidar system.
ST’s VL53L0 module is simple and easy to use (6 valid pins), provides an I2C interface, is equipped with a full set of API drivers and technical documents, making system integration fast and simple. The module package supports the reflow soldering process, complies with the RoHS hazardous substance restriction standards, and is fully compatible with quite a lot of glass covers and appearance designs.
Unlike traditional infrared proximity sensors, the color and reflected light of the target object won’t have an effect on the distance measurement results. But its effective range and accuracy in large part depend on environmental conditions and target characteristics, such as reflectivity and size, and sensor configuration. (The accuracy of the sensor is specified as ±3% at the highest, and it is over ±10% under the next best conditions.)
The internal laser emits non-visible light with a wavelength of 940nm, which does not harm the eyes, gets rid of the problem of distracting people from emitting red light with other infrared proximity sensors, and enhances the anti-interference performance of external light sources. The sensor’s digital architecture and automatic compensation function make it still have a high performance in scenes with high ambient light intensity.
The sensing capability of VL53L0X can beef up quite a lot of functions, including gesture sensing or proximity of quite a lot of innovative user interfaces; wall detection, cliff detection, and collision detection of household appliances such as sweeping robots; bathroom products, such as faucets, soap dispensers, and Cell phones and flushers; other target applications include laptop user presence or power switch monitors, drones and Web of Things (IoT) products.
