# OpenSimpleLidar

Open Hardware scanning laser rangefinder.  

Its parameters:  

* 5 scans/second

* 180 measurements per rotation (2 deg anglular resolution)

* Maximum distance - 4 m

* Measured accuracy ~3-5 cm at 3 m (depends upon the color of reflecting surface).

This device is really cheap - its components cost less than $30.  

**UPD from 2023: Cost of the image sensor TSL1401CL increased very mush, so total price can be higher!**  

See "TotalBOM" with price calculations.  

  

Now I'm updating the documentation for this LIDAR.  

Some of it I'm writing to the project wiki: https://github.com/iliasam/OpenSimpleLidar/wiki  

[Please take the simple survey about assembling instructions](https://docs.google.com/forms/d/127PN3ydydF8poReQAPeC-vXDqIst-CIAj8u08tnh1lM)

This Lidar is using **triangulation method** for measuring distance to objects. It can be shown by this picture:

If you need LIDAR with increased speed and range, see this project: https://github.com/iliasam/OpenTOFLidar  

Please leave your feedback if you will be able to build this Lidar - I need more feedback about assembing instructions.
