Description:
Waveshare TOF (time of flight) Mini Laser Range Sensor is a TOF-based (time of flight) mini laser ranging sensor with embedded MCU and ranging algorithm, which the measuring range is up to 7.8m and the accuracy is up to ±4cm. It supports UART or I2C communication bus, features longer measuring distance and higher light interference tolerance capability due to its ultra narrow FOV, suitable for either indoor or outdoor condition. And its ambient light tolerance is up to 100K LUX.
Waveshare TOF (time of flight) Mini Laser Range Sensor sensor can be widely used in applications like common distance measuring, robot obstacle avoidance / route planning, as well as drone altitude setting / ceiling detection, and more.
