Finally decided to make an account and start asking silly questions. I've been reading this forum for quite a while now as a guest.
I'm working on a project, in which I would need relatively high precision & resolution on ~1.4-3m distance. The detail of the results should be .-something of a millimeter. The goal is to detect the distance in millimeters and there are four different modules sensing distance to each other. In two tf them the working distance is 1400-1650mm, and the rest two are working 2000-3000mm apart. The reflecting surface can be altered to fit to desired sensor (IR, Laser, sonar etc). I'm even wondering, if I could get more precise result by using sensor on both ends, and calculating the average of each result.
If I were to use something like LV53L1x ToF-sensor, the resolution is just 1mm. Making calculations on 1mm resolution on each sensor, I end up with more than 1mm of overall deviation. Therefore I think I would need sensors of which resolution should be around 0.1-0-5mm? Anyone got any suggestions?
I saw this today (IDS3010 - Measurement becomes nano precise - YouTube) and I was wondering, whether there are any cheaper alternatives? I'm hoping for price range under 25€/sensor. (Ideally even under 10€) That would keep my overall budget somewhat reasonable.
