The invisible sensor for irrigation and water stress management

MiniMETOS Soil station

With miniMETOS all the potential issues and stress events can be identified before they occur or become visible.

miniMETOS is a combination of the most essential sensors for irrigation and water stress management. It permanently measures soil temperature & volumetric water content (VWC) with Pessl Instruments Soil Moisture Sensor PI54-D and Watermark (soil moisture suction) in near real-time.

The installation of a logger can be completely underground (invisible); therefore, it is a perfect installation for golf courses, parks, homes & gardens, as well as in agriculture where vandalism and theft could be a problem.

The device is powered by a high capacity primary battery with an autonomy between 6 to 12 months, and provides actionable data, such as the exact amount of moisture and the soil temperature in each inch/cm of the measurement area, to help you plan the irrigation event and to warn you about possible stress points in a timely fashion.
