Sure. It has a capacity of two.
In a perfect world, 8 meters would be sufficient. The ideal environment is one in which the measured object is highly reflective to the laser and has low illuminance. In practice, the amount of light in the environment and the reflectivity of the object being measured to the laser have a direct impact on the measurement range and accuracy.
It simply measures the distance between it and the obstacle. He can't tell if the person in front of him is a person or an object, but he can use the function of measuring distance.
It's in the "product description" section.

It took me some time to figure out how to make use of this. There aren't a lot of documents on it, or, more importantly for me, examples of how to use it in various languages. On the Raspberry Pi, I'm using Python. br>br>However, I did find instructions for this on one of the company's similar products. I was able to get it to work for my project. br>br>Would have given it five stars if it hadn't been so difficult to figure out how to use.
Well-focused and precise. It's the best I've come across. This technique makes use of infrared light that is well focused. emitters in the color red This device also returns the signal strength in addition to the distance. I discovered that if I ignore any readings with a signal strength of less than 200, the measurements are quite accurate and stable. Signal strength in the tens of thousands is normal, so 200 is a poor reflection. I made use of an infra-red camera. To see the target point, you'll need a red (night vision) camera.
It's a compact lidar that works well with my Pihawk 2. Because it is not I2C compatible, it receives four stars. On a serial connection, it works flawlessly. Aside from that, it makes landings buttery smooth.
I was unable to use i2c. I wanted to use i2c, but the unit wouldn't connect, and the documentation on the website is only for serial communication at 115200. As a result, I reverted to Serial mode, where the unit performs admirably. There is a lot of consistency. The beam width is narrow, which is exactly what I needed for my project. With the exception of the i2c issue, I am very pleased.
For $19, the TF Luna is a fantastic device. On my hobby robots, it performs far better than any sonar. TF Mini was the first device I tried. The only thing I didn't like about it was that I couldn't get it to respond to commands no matter what I tried. Also, it samples continuously (I assume Luna does as well), so I built a pMOSFET switch to turn off power unless I needed it.
I'm going to get another unit for one of my other quads. This lidar unit has exceeded my expectations.
Even though the specifications say 20cm to 800cm, the measurement is accurate to within 2cm.
It does exactly what it says on the tin. A more standardized connector would be preferable.
