  1. TF02 is a single-point ranging LiDAR, used by drone for measuring the relative altitude from the ground, ensuring the stable altitude. It is available for the following flight control brands: Pixhawk4, APM, TopXGun, EFY Technology, JiYi, aiAero, DAISCH, etc. TF02 has the following features: <iframe width="560" height="315" src="https://www.youtube.com/embed/OHZHhBZF2SE" frameborder="0" allowfullscreen></iframe> Distance Measurement Performance: 1. Longer indoor and outdoor measurement range (indoor: 22m; outdoor: above 10m); 2. Lower noise. Almost no abnormal data within effective range; 3. Sound signal discrimination algorithm for identification of abnormal data; 4. Higher repeated accuracy of distance measurement Overall Performance: 1. Higher protection level, up to IP65; 2. Pesticide corrosion resistant, with special enclosure material capable of resisting corrosion of most of the pesticides; 3. Work normally even with optical window being contaminated by dirty water, sludge and other pollutants; 4. Shock resistance. Unique design makes it more solid, shock resistant and infrangible; 5. Additional function of bootloader to facilitate further software upgrade;
  2. As I known, TF01 is design to drone's height fixing, specially, instead of a general distance detecting device. It works well under 100 klux sunlight outdoors. It is protected from the dust, water, and corrosion. It fits differenct ground suface: plant, grass, raod, mud, Comparing the shape, TF01 is like a mass production product with integrated design. I got the response from Benewake's FAE "There are some significant differences between our TF01 and other laser options (such as lightware or lidarlite): 1. The product TF01 has a complete system, containing a protective shell made of materials with a high transmittance of infrared, which doesn't affect the optical performance. 2. The product TF 01 has been widely used in the height fixing and the terrain following of the drone, especially in the agriculture. As a considerably mature product in the market, our TF01 has collected a large amount of experience and actual data in different situations, which has been taken as feedback for further improvements of the product itself. Meanwhile to guarantee the reliability of the TF01, we conducted a rigorous seismic test and the performance of TF01 turned out excellent."
  3. I cite a product below which is emploied as terrain following and height fixing for drones. [FW below] DE LiDAR TF01, a product widely known in the drone and smart devices industries, was an immediate success upon its appearance at the show. Its application in altitude measurement, drone terrain following, distance measurement and security sensors were particularly attractive to visitors from all over the world.Image 1: DE LiDAR TF01’s Altitude Measurement ModuleThe module, already in mass production, can work with flight controllers like Pixhawk and TopXGun andaddresses the difficulty of altitude measurement that many drone and flight controller producers experienced. Unlike traditional altitude measurement solutions such as GPS, barometers and ultrasound, the module can detect and refresh the distance between a flying drone and crops on the ground in real time at a frequency of 500 times per second. It also ensures that the drone can fly at a stable height with an error in centimeters. The module, which is free from the interference of temperature, ambient light change and airflow, can also significantly improve the work performance of drones.During the show, TF01 was synchronously launched for sale on global hardware platforms likeSeeed (https://www.seeedstudio.com/) and RobotShop (https://www.robotshop.com/) and dozens ofdistributors kick off business talks with Benewake.Benewake began to deploy a patenting strategy overseas for its LiDAR product as early as 2014. By far, it has built an independent intellectual property system (through overseas patents) and passed a complete range of European and American product certification (FCC, CE, etc.), which ensures the legitimate use and sale of the product internationally.Website: www.benewake.com
