Sounds reasonable (or even quite good) for such a cheap sensor. Does yours come with a datasheet that specifies accuracy limits? The datasheet on the Sparkfun website claims "the ranging accuracy can reach to 3mm", but does not give any guaranteed limits - and I believe there are lots of clone parts thay may be even worse. cu Michael -- Some people have no respect of age unless it is bottled.
