Laserski senzor baziran na principu merenja vremena reflektovanog zraka.Primena ima mnogo naprimer kod mašina za merenje odstojanja od radnog predmeta,razna merenja udaljenosti kod dronova itd...
Šalje IC laserski signal i meri vreme za koje će se vratiti reflektovani od predmeta. Princip je sličan ultrazvučnom merenju udaljenosti samo je naravno različit nosilac , rezolucija i daljina merenja. Za komunikaciju sa arduinom ili nekim drugim razvojnim sistemom koristi i2c bus.
Karakteristike:
Čip: L53L0X
Udaljenost merenja: do 2m max (zavisi od površine od koje se reflektuje zrak)
Rezolucija: 1mm pri daljini od 2m


Originalni opis:

The VL53L0X from ST Microelectronics is a time-of-flight ranging system integrated into a compact module.

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. Our breakout board addresses these issues, making it easier to get started using the sensor, while keeping the overall size as small as possible.

PIN description:

VDD: Regulated 2.8 V output. Almost 150 mA is available to power external components. (If you want to bypass the internal regulator, you can instead use this pin as a 2.8 V input with VIN disconnected. )
VIN: This is the main 2.6 V to 5.5 V power supply connection. The SCL and SDA level shifters pull the I2C wire high to this level. GND: The ground (0 V) connection for your power supply. Your I2C control source must also share a common ground with this board. SDA: Level-shifted I2C data line: HIGH is VIN, LOW is 0 V SCL: Level-shifted I2C clock line: HIGH is VIN, LOW is 0 V XSHUT: This pin is an active-low shutdown input; the board pulls it up to VDD to enable the sensor by default. Driving this pin low puts the sensor into hardware standby. This input is not level-shifted.
