ladyada, i'm dying to know - how can we make this sensor work in Midisense? there must be a way to do it. i and others already have a couple of these IR sensors and personally i'd be willing to experiment but this would really really help me out.

This sensor takes a continuous distance reading and returns a corresponding analog voltage with a range of 4cm (1.6") to 30cm (12"). The sensor package includes a JST 3-pin connector, three pre-crimped wires, and a booklet with detailed information and examples.
how can we make this work?Absolute Maximum Ratings
