Sensor for Bath Tap Mixer: Ideas welcome!


I am trying to figure out the best way to put a sensor on a bathtub tap mixer so to use the tap a knob to control analog values. The tap will not be used for water anymore, so don't worry about waterproof problems.. I am sure there is an easy way to do this, but my trials and mistakes didn't really help. Any ideas?


The tap will not be used for water anymore,

That's a pity, otherwise you could measure the temperature and the flow to get an indication of the position of the knobs :)

seriously you need to find some way to connect the knob to a potentiometer, either direct or through some gearing (to allow multi rotation).

Bathroom taps are becoming a style statement these days. There are a variety of models available in this particular accessory kind. The latest one in this category is the tap which has a sensor. Bathroom Supplies
