    Great for smart cars!

    posted by ObiTwice on 05/02/2013 Certified Owner

    Involvement:General (knows how to use it) - Ownership:1 day to 1 week

    Pros:
    It is very cheap, pretty easy to use with an arduinio. Not very precise, but with a constant measuring fault it is easy to calibrate. Works great for smart-cars. Works good up to 60-80 cm. Lots of guides on the internet.
    Cons:
    Not as precise as calmed in the advertisement. Is not that great for use in a qaudcopter because of its short range.

    Good cheap product

    posted by Ramvanios on 03/27/2013 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

    Pros:
    It is an amazing sonar module! Price is great! The measurement is very accurate, with margin of error around 1cm. It reaches from 1cm to over 3m! (as far as I have tested). It's easy to find codes on the internet that work for it, and it's very simple to us...
    Cons:
    None that I remember.

    posted by chffelix on 03/24/2013 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

    Pros:
    Relatively small, cheap and well performing ultrasound distance measurement module. Works as advertised on its datashet, which can be found here: https://docs.google.com/document/d/1Y-yZnNhMYy7rwhAgyL_pfa39RsB-x2qR4vP8saG73rE/edit
    Cons:
    None so far, but it works best when obstacles are flat (the echo pulse shows much less jitter between consecutive readings)
