AgroBee-L
Radio modules used for the activation of valves and other irrigation elements,
as well as the reading of sensors and meters.
The AgroBee-L replaces the AgroBee as a standard solution incorporating better features.
Description
The AgroBee-L modules work with LoRa radio modulation, which operates in the 868 MHz, 433 MHz and 915 MHz free bands, obtaining radio coverage of up to 2500 m between two points (depending on the orography).
It is the best solution to save costs as a substitute for the cable, avoid incidents of the microtube installation, overcome obstacles, expand sectors, perform temporary installations, etc.
Its low consumption allows it to operate with a solar panel integrated in the module, storing the energy in supercapacitors or battery (depending on the model), offering a long operating life.
Currently, the AgroBee-L modules can be incorporated into the Agrónic 2500, Agrónic 5500 and Agrónic Bit Con fertirrigation controllers.

System
The AgroBee-L system consists of a coordinator device located in the controllers and by field elements with different functions, depending on the model in question.
This system does not include the use of repeater elements, so all modules must connect directly with their coordinator.
The field modules manage their consumption by activating the communication in the precise time of the exchange; the rest of the time, they are asleep or attending to irrigation control.
The maximum number of modules that an Agrónic controller can manage is 20 units in standard mode, which can be configured as modules of any of the available types. There is also a priority mode, which makes it possible for the modules to communicate more often: in this case, the number of modules (10) is halved.
To use AgroBee-L modules, it is necessary to assign their outputs to the sectors or generals of the controller in question, and their inputs to the digital, analog, or counters sensors.
