Hi everybody !
Here is my issue : I would like to get a very precise measure of a distance with the HC-SR04 : for that, I use more than one of them but now I would like to know how I can use them to get the best value with the minimum of resources.
Do I do a lot of measures from each HC-SR04 and use them all?
Do I get 10 value from each sensor and delete the min and the max?
Do i do one measure from each sensor with a good filter so that it will be quicker?
Do I add sensors?
Any better idea?
What is the best solution knowing that it does not have to be real-time (I can wait 1-2 seconds), that the place taken by the sensors is not an issue neither and I can add as many as I want (up to 5). By the way, the precision should at least be of half a mm.
Of course, whatever the solution chosen, I will then filter the result.
Thanks in advance for your help and have all a nice day
