An ultrasonic range sensor that can detect objects from 3cm to 3m away.

The sensor can be used with and Arduino or a Picaxe microcontroller to calculate how far away objects are. The sensor is accurate enough to detect a 3cm broom handle at a distance of 2.4m!  

Easy to connect to the Picaxe. Templates are available to show the easy connect to the Picaxe. Please inquire.

Lots of support material is also available for connecting to an Arduino and programming it.
