Wireless soil moisture transmitter

PRX SOIL NET

Knowing, with precision, if the quantity and frequency of the irrigation is optimum for each crop, is the basis of precision irrigation and the profitability of irrigated crops.

The PRX-SOIL transmitter for moisture sensors helps us to obtain this data. It has the capacity for up to 4 Watermark®-type sensors and sends information to the IProx Irrigation application, taking advantage of the same radio network used by the PRX-VALVE controllers

  • Reading of up to 4 Watermark®-type sensors for each machine
  • Radio communications with a base station connected to the controller. 
  • Mesh radio communications with up to 4 hops. Requires an IProx controller with a radio base station or another PRX-VALVE device in a radius of up to 2000 m, giving  a total range of 8000 m between the pumping station’s IProx controller and the furthest PRX-VALVE device

PRX-SOIL provides the IProx Irrigation web application with precise data regarding the level of soil moisture, integrated with the rest of the information on the pumping stations, pivots, coverages, meteorology, etc.

Low operating cost thanks to its integrated solar panel and the economic long-lasting batteries.

From a sole base station connected to an IProx controller, it is possible to collect soil moisture data from up to 8km away.

EXAMPLES OF USE

  • Water and energy savings due to the incorporation of the real irrigation needs of the crop in the irrigation planning process.
  • Precision farming through the incorporation of real soil moisture data according to the irrigation recommendations for each sector and crop.

FAQ’s

P: How often are the soil moisture sensors read?
The user can configure the frequency of the readings. Since, with the exception of sandy soils, the filtration, evaporation and consumption of water by the crops are slow processes, in the majority of cases 1 or 2 readings per day is enough to obtain the information necessary to optimise the quantity and frequency of the irrigation. Moreover, a greater frequency of readings generates charts with more points, which are easier to interpret. A reasonable frequency could be a reading every 4 hours (=6 readings a day).

P: Can the soil moisture data be taken into account in the irrigation programmes set in IProx Irrigation so that they stop if the moisture level exceeds a configurable threshold (due to a storm, for example)?
Yes. The irrigation will pause for those sectors in which it has rained in the same way as it stops when the reservoir water level is lower than the established minimum. Yet another measure that helps to stop waste.

P: How many PRX-SOIL devices can be connected to the same radio base station?
The technical limit is around 100 PRX-SOIL or PRX-VALVE devices per base station. This amount is rarely reached on the same plot with one pumping station and one IProx controller.

P: Do the PRX-SOIL devices include the sensors?
The Watermark® sensors are bought separately and the number purchased does not need to tally with the number of PRX-SOIL x 4.
