Product Description

Lidar Range Finder Sensor Module TF-Luna

Parameters

Peak current: 150mAAverage power: 350mWDefault baud rate: 115200Data bit: 8Stop bit: 1Parity check: NoneLight source: VCSELOperating temperature : -20°C~75°CCertification: CE,FCC,ROHS ACCURACY ISSUE

1. THE FOV OF TFLUNA IS 2°, THAT MEANS THE LIGHT SPOT IS DIFFERENT ACCORDING TO THE DISTANCE;2. IN ORDER TO INSSURE THE ACCURACY, THE SURFACE AREA OF OBSTACLE MUST TO BE LARGE THAN THE LIGHT SPOT.3. ON THE OTHER HAND, TWO OR MORE DIFFERENT DISTANCE OBSTACLES IN THE LIGHT SPOT ALSO CAN AFFECT THE ACCURACY. Small Size but Yet Powerful

Low-cost ranging L iDAR module with 0.2-8m operating range<=5g，suitable for scenarios with strict load requirements≤0.35W, suitable for battery-powered or low power consumption scenarios35mm*21.25mm*13.5mm easy to install and integrate

Package included: 1 X Benewake Lidar Range Finder Sensor Module TF-Luna 1 X Cable

Single-Point Micro Ranging Module 0.2 to 8m

Ranging Principle

TF-Luna is using Time of Flight (ToF) principle to measure the distance and it periodically emits near infrared modulated waves. TF-Luna calculates the time by measuring the phase difference between the original wave and the reflection wave and uses that time to get relative distance, as shown in Figure 1.

Ranging Characteristics

If the light spot reaches two objects with different distances as Figure 2, the output distance value (Dist) will be abnormal, which may cause error for high-accuracy applications. Please try to avoid this situation for better accuracy and performance.

Product Characteristics

The product is built with algorithms adapted to various application environments and adopts multiple adjustable configurations and parameters so as to offer excellent distance measurement performances in complex application fields and scenarios.

Specifications of Lidar Range Finder Sensor Module TF-Luna

Benewake TF-Luna LiDAR Module Range Finder Sensor Single-Point Micro Ranging Module for Arduino Pixhawk 5V UART IIC InterfaceTF-Luna is a single-point ranging LiDAR, based on TOF principle.With unique optical and electrical design, it can achieve stable, accurate and highly sensitive range measurement.

Applications

Smart Trash detection and trigger

TF Series Lidar developed by Benewake achieves intelligent and touch-free garbage recycling. It provides two solutions for monitoring a trash bin – detecting if lid is open, and measuring the height of garbage within. Benewake Lidars have already been applied on smart trash in many cities. These smart trash, not only being able to facilitate touch-free waste disposal, will also send real-time data to garbage trucks and request garbage collection when they are 80% full. Therefore, seamless garbage collection and transportation becomes possible.

Introduction to Intelligent Roadside Parking sensor

A Roadside parking management system is the one that manages parking and operations based on IoT, cloud computing services, and intelligent sensor technologies.The management system utilizes LiDAR and camera to snapshot parking spaces, identify license plate numbers, and start timing for individual cars when they navigate into the area of management.

Smart Toilet

In terms of intelligent detection function, the public area of public toilets is equipped with an interactive display, from the display can allow toilet personnel and managers to intuitively see the use of various toilet spaces for men and women, the use of the third toilet and mother and child rooms, the total passenger flow of smart public toilets, air quality, water, and electricity consumption and other relevant information.It is convenient for the public to understand the overall environment of public toilets, and managers can also temporarily monitor the cleaning of public toilets.
