If your μMETOS Blue was intended for soil moisture monitoring it comes with a set of soil moisture
sensors connected to the main unit. The sensors connected to it can be EC 5, HS10, 5TE from Decagon
Limited and/or Watermark sensors or vacuum tensiometers.

This sensors can be connected to the μMETOS Blue itself or if it is needed because of the installation or
because of the number of sensors – they can be connected to an extension box on a serial bus
