@Rahul Tripathi: Please search (CTRL+F in most browsers, when on the page) the previous comments for “potholes”, you will notice we already answered another community member about a similar inquiry. Please note that angle of sensor, surface condition, number of sensors and velocity of sensor on road all are very important details to determine if this is doable. The two responses in the comments should provide enough information to get you started about figuring out what you will need.
@Melvin: We recommend that you check out the instructions manual for the device, especially page 5 and page 9. They give details of signal strength threshold and received strength. You should be able to read those using I2C commands.
How would I get it to output signal strength in your code?
@Rady Price: How and what you can access depends on which version of the LIDAR-Lite you are using. If you are using a version 1/2, please check the v2 doc here (pages 28, 29, 36). If you are using v3, please check the recent blog comments (March 10th, 2017) about strength. The answer to Melvin should be helpful.
Thanks for all the help, i have one question too. Does the LidarLiteV3 have a reference LED like the V2?
Dear Friend, I want to know, The LIDAR lite v3 can be use for vegetation/crops and it be compatible with ardunio.
@Dr Naveed Tahir: The LIDAR-Lite v3 is indeed compatible with Arduino (as you can see in this tutorial / blog article). The LIDAR-Lite v3 is meant as a simple range measurement device and does not penetrate vegetation/crops or help detect them.
@Jerry Garcia: The design of the LIDAR-Lite v3 did not change much from the v2. The controller, library and interface cable changed, but the transmitter/receiver technology did not. The Theory of Operation (page 4 of the manual) mentions the reference signal being transmitted directly to the receiver, so the answer is most likely “yes”.
Can the lidar lite measure water level with Arduino products?
@george: Maybe, but it depends on many factors. We recommend that you search (typically CTRL+F in most web browsers) the other comments on this page for information after water level measurements. The word water should give you good results.
I am stuying the specs right now. What is meant with virtual detector size of 1mm? How can I calculate the beam divergenz of the receiver from the given specs?
Thanks for the great help here.
@Freddy: You can see the specifications here, including beam divergence, which is reported as 4 mRadian x 2 mRadian. This would make it ~0.2292 degrees x ~0.1146 degrees.
Hi,
Can I make Lidar Lite V3 moving 360 degrees with full field view like other Lidars such as SWEEP V1, RP Lidar, Hokuyos, etc. with appropriate motors, gears and casing? Can I use the same for mapping using SLAM algorithm? If yes, Then what are the primary considerations I should follow?
@Rohit: Yes, you can. You would need to use either a slip-ring or a rotating mirror (set perpendicular to the LIDAR). You can also even add tilt to the angle of the rotating assembly to provide 3D scanning, too. As for references on SLAM, you check out this, this, this, and this.
Thank you for your help:)
Hi is it possible to display the distances on an LCD both the lidar and LCD connected on an arduino? Thanks
@mike: Yes it is. As long as you have enough I/Os for both your sensor and LCD, you should have no issues. To get you started, you can use the example code for this blog article and the code for this one. If you need more technical help, please create a new topic on our forum. You can do so here (general microcontroller stuff), here (sensor specific) or here (LCD specific).
Hello Sebastien!!.. I want to make a precision laser scanner for topography applications.
I would like to know how to determine the angle of each measurement very precisely so as to obtain the X, Y, Z coordinates.
What sensor and hardware you need.
Regards!
@Gustavo: For technical questions concerning integration of a sensor, we recommend that you create a new topic on our forum here.
is it LIDAR-Lite Laser Rangefinder is useful for crack detection in roads…
