1. Time-of-flight (ToF) ranging module based on VL53L1X design, accurate ranging range up to 4m, fast ranging frequency up to 50Hz, I2C interface communication, low power consumption 2. VL53L1X is the third-generation Flightsense technology time-of-flight sensor launched by ST. Compared with the second-generation VL53L0X, VL53L1X expands the TOF ranging length to 4 meters, and the ranging frequency can reach 50Hz, which is different from the traditional ranging sensor. 3. VL53L1X adopts ST's latest ToF technology and integrates physical infrared filters and optical components. It can perform distance measurement regardless of the color and reflectivity of the target, and has stronger anti-interference ability. 4. Support IC interface communication, and the module switch can be controlled through the IC port 5. On-board level conversion circuit, compatible with 3.3V/5V working level VL53L1X Distance sensor parameters: Working voltage: 3.3V/5V Product size: 20mm x 24mm Through hole size: 2.0mm Ranging range: 40~4000mm Ranging accuracy: ±5% Ranging time (min): 20ms (short distance mode), 33ms (medium distance/long distance mode) Ranging angle: 27degrees wavelength: 940nm Working temperature: -20~80Celsius [My use]: mobile robot (fast ranging and obstacle detection, walking on walls), user detection (personal computer/notebook and other equipment user detection wake-up, switch machine), robot (obstacle detection), 1D gesture recognition, Camera (low light AF assist, video focus tracking assist) Colour:blue Material:PCB Range:4M/2M Package Contents: 3 x VL53L1X Distance sensor 3 x Connecting wire Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
