# VL53LXX Time of Flight (Tof) Distance Sensor Peripheral Component The [Vl53L0X](https://www.st.com/en/imaging-and-photonics-solutions/vl53l0x.html) is a Time-of-Flight (ToF) distance sensor. It is a sensor that can measure distance from a target object without touching it. The sensor uses a laser to send a pulse of light and measures the time it takes for the light to reflect back to the sensor. The sensor can measure distance up to 2 meters with a resolution of 1mm. Because of the way the sensor works, it is able to measure multiple distances at the same time. The sensor can struggle with outdoor use, as sunlight can interfere with the sensor's ability to measure distance. The sensor is also not able to measure distance through glass or other transparent materials. ## Example The [example](./example) shows the use of the `Vl53l` component to communicate with a VL53L0X time-of-flight distance sensor.
