Affordable remote measurement of soil moisture, EC and temperature for horticulture and agriculture (and other applications). This type of measurement is needed to use not more water and fertilizer than really needed for the crop. This also saves a lot of energy for pumping. Irrigating based on data takes out the guesswork and thereby saves expensive production losses, and increases quality and quantity of the yield.
Developed by SensorTagSolutions
The AquaTag remote system consists of sensors for pots, open soil and for plugs. They measure water%, EC (electrical conductivity, a measure for the amount of fertilizer) and send the data to the webplatform, aquatag.net. The systems works worldwide and data (and history) can be monitored and analyzed on any type of screen.
See more information about this level and the TRL and SRL levels.
The sensor measures the complex impedance between two metal rods that are inserted into the soil or substrate. The data are sent to a web server where the water content and EC are calculated. In one of the two metal rods, a temperature sensor is embedded, the temperature is also sent to the web server. On the website www.aquatag.net the data can be monitored in graphs, and as a ‘heatmap’. The sensor works on 3 AA batteries that need to be replaced or charged annually. There are different versions of the sensors for different applications: a long one for open soil, a short one for pots, and one with needles for seedlings in trays.
Limitations/conditions under which this innovation does not work or is less effective
There needs to be cell phone coverage (3G or GPRS). If this, however, is not present a solution can be provided.
Added value
Our sensors are low cost, and very easy to implement and use and can, therefore, be used to not only measure in one place per field, but in several places, so that reliable average values, and an image of the moisture and EC distribution, are obtained, which is essential information for irrigation decisions.

The main components of the system have been tested separately, and an initial integration exercise has been conducted.
