'Power filters' are simple RC filters you can solder directly on the sensor,
they help eliminating electric noise. Since the analog output of the sensor
depends on the voltage with which it is fed, the cleaner the supply voltage,
the better the analog output.
I don't know which sensor you're gonna us, but assuming it works like the
MB1000 or MB1200, you will find a lot of useful tips inside the datasheet and
in the tutorial page.
I'll start cleaning up my mess and a few short tutorials should be on my github
by this evening.
Best,
Alex

thing you really want to take into acount is the fact that sensors
interract with each others, you therefore need to chain them properly.
