The sensor you have is an analog one, which makes it very easy to interface. Just do an A-to-D conversion.

The output voltage is NOT linear with respect to the distance, it's . I have some 8-bit data on one of these that I collected that can demonstrate:

Value Distance
1-21 out of range
22 38"
23 35.5"
24 33.8"
25 31"
30 22"
40 16"
50 12.8"
60 10.5"
70 9"
80 7.9"
100 6.2"
120 5.15"
140 4.3"
159 3.5"
160-255 out of range
