TOF (time of flight) Mini Laser Range Sensor, UART / I2C Communication Support, Long Range

TOF Mini Laser Range Sensor

long range | short blind zone | stable/accurate/sensitive | indoor/outdoor

Product overview

This 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.

This sensor can be widely used in applications like common distance measuring, robot obstacle avoidance / route planning, as well as ceiling detection / stacking detection, and more...
