Soil moisture sensor

The sensor consists of corrosion resistant electrodes embedded within a specialized granular matrix. Water in the soil exchanges with the sensor matrix, providing a measurement of centibars (or kPa) of soil water tension. It requires no site calibration or maintenance and it’s durable and reliable for harsh soil conditions.

- Operating range: 0 – 239 cb or 0 – 100 %
- Accuracy: 1 cb or 0,1 %

Sentek Drill&Drop soil probe

The Drill&Drop soil probes of the leading Australian manufacturer Sentek show the soil water content every 10 cm depth – e.g. at 10, 20, 30, … down to 120 cm. The water content is displayed in litres per square meter. This way you have information how much water you have available in the soil at any given moment.

- Moisture sensor resolution: 1:10000
- Moisture sensor precision: ±0.03% vol.
- Temperature sensor resolution: 0,3°C
- Temperature range: -20°C ÷ +60°C

Solar radiation sensor

By taking into account solar radiation data, as well as air temperature, air humidity and wind, Meteobot® calculates how much water is evaporated from the soil and transpired by the plants every day (so called “evapotranspiration”) by using FAO Penman-Monteith equation. When you know the water losses from the soil for a certain period, you can find out how much you need to irrigate (e.g. 5 days x 4 liters evapotranspiration per day = need for 20 liters of irrigation).
