WaveThe TOF Laser Range Sensor (B) is a TOF-based (time of flight) laser ranging sensor with an embedded MCU and ranging algorithm, which is capable of offering up to 15m measuring range, ±2% accuracy and 1mm resolution.

It supports UART or I2C communication bus and features a longer measuring distance and higher light interference resistance capability due to its ultra-narrow FOV, suitable for either indoor or outdoor (dry!) conditions.

This sensor can be widely used in applications such as common distance measuring, robot obstacle avoidance/route planning, drone altitude setting/ceiling detection and more.

We also offer the original ToF sensor from Waveshare.
