one wire vibration sensor

hi is there anything out there like the DS18S20 one-wire bus but for vibrations i am currently using upto 16 DS18S20 to monitor bearing temps on conveyor belts but would like to add also vibrations the piezo vibration would be a pain on 16 vibrations at same time

thanks

Nothing directed towards vibrations as such but there is a 1 wire A/D that can be used to feed back the measurements from a vibration sensor.
