How to measure the distance up to 200m (with arduino)???
1. What would you use ???
2. Is it possible to modify the PING))) sensor to be able to measure such distance ???
3. Do you think, that this radar kit www.hobbytron.com/r-sg7.html could me modified to do the job ??? There is a 'pdf' file for more information.
4. Or would you use laser - how ???
Thank you in advance for you answers/suggestions.
