VL53L0X Lidar distance sensor uses laser ranging techniques to measure the range of a target within 2 meters. It measures the distance by using the time of flight principle, thus, also called TOF (time of flight) laser-ranging module.
Key Features
- It is an Integrated module of small size
- Lidar distance sensor has embedded microcontroller
- It provides an absolute measurement of up to 2 meters.
- Its integration is easy due to the use of the 12C interface.
- 12C interface controls data transfer
- It has programmable 12C addresses.
- Lidar distance sensor uses only 1 power supply.
Specification
- Working voltage range: 2.6V to 5.5V
- Operating Current requirement: 10mA
- Communication protocol: I2C
- This sensor has an in-built voltage regulator
- Dimensions:4.4×2.4×1.0 mm the module
- VL53L0X has an integrated SPAD array.
- SPAD array accurately distinguishes between different photons within tens of picoseconds.
- The laser used here is a 940 nm VCSEL which has the feature of invisibility and it is very safe for the human eyes.
