Accurate distance sensor ... low power

f_jones

Hi,

 

Any thoughts on this ... I'm trying to find a sensor to work with an Arduino  (or similar) Micro-controller.  The sensor needs to measure the distance to 500microns over a range of 50mm. Ideally measurements would be made at a >500Hz and the power consumption would need to minimal (or minimised).  best I can find so far are all at 10-30V range with power consumption of about 0.5Watts.

 

Thanks

Mar
