Miniature TOF Laser Range Sensor 4m UART Waveshare

Miniature TOF MINI laser distance sensor 4m

A compact distance sensor based on innovative Time-of-Flight (TOF) technology, offering precise distance measurements in the range from 2 centimeters to 4 meters. The device integrates its own controller with an advanced measurement algorithm, communicating with the host system via a convenient UART interface. It is ideal for indoor applications, finding use in mobile robotics, obstacle detection, as well as positioning and tank level monitoring systems.

Key features:

High precision and cost-effectiveness

The module offers an excellent price-to-performance ratio. It guarantees high stability of results, accuracy of ± (1% ~ 3%), and excellent measurement sensitivity with minimal energy consumption and a supply voltage range from 4 V to 5,6 V.

Wide range of applications

The sensor is perfect for modern electronic systems. It can be used for effective obstacle avoidance in autonomous robots, path planning, altitude detection in drone-based projects, or container fill level control.

Compatibility with microcontrollers and microcomputers

The TOF MINI module is fully compatible with popular development boards. The applied UART communication standard makes integration with single-board computers, such as Raspberry Pi, fast and seamless.
