sharp infrared distance sensor

Today I tested a infrared distance sensor.

I am using a Sharp2d120x, with a range from 4-30cm. I soldered its ground and source to J2, as the sensor

requires 5V to operate, and its output (analog voltage proportional to the distance) to an analog input.

The sensor works quite well, except it cannot reach the highest 5% of the midivalue, but this is not a

problem for me.

Greetings Geth

PS: The additional yellow wire and the capacitor between the (other) yellow wire and the grey one is

obsolete, I only put it there to test reducing noise. The capacitor between 5+ and ground is sufficent

to make the jittering drop under 7bit resolution, which mean no noise.
