1. This is a laser ranging sensor based on TOF (Time of Flight) technology. 2. Built-in controller and ranging algorithm, ranging up to 15m, accuracy up to 2%, resolution up to 1mm. 3. High stability, high precision and high sensitivity distance detection 4. Support UART or I2C interface communication, in UART mode, support active query output; in I2C mode, support up to 8 devices in parallel 5. It supports UART and I2C communication, with ultra-small FOV angle, which makes the distance farther and stronger against light interference. It is suitable for both indoor and outdoor environments. It can be used as a ranging tool for distance detection, and also as a robot for obstacle avoidance/route planning. , Can also be used in the fields of UAV fixed height/ceiling inspection.
