This is a laser distance measurement sensor based on TOF (time of flight) technology Supports UART and I2C communication, with ultra-small FOV angle, making the distance farther, stronger in anti-light interference, suitable for both indoor and outdoor environments, and anti-ambient light ability up to about 100KLUX illumination High cost performance: 0.02m-7.8m long-distance low-cost distance measurement module Highly stable, high-precision, and high-sensitivity distance detection Can be used as a distance measurement tool for distance detection, as well as for robot obstacle avoidance and route planning, and can also be used in drone height determination, ceiling detection, and material level measurement Typical ranging range: 0.02m - 7.8m Typical ranging accuracy: 0.02m - 7.8m4cm Wavelength: 940nm Field of view (FOV): 2 - 3 Communication interface: UART, I2C, I/O Refresh frequency: 50Hz Power supply voltage 4.3V - 5.2V Colour:Black Material:ABS Package Contents: 1 * Laser Range Sensor Module Kit 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.
