Know the AgroBee’s new version, the AgroBee-L
This new version works with LoRa radio modulation and operates in the license-free bands 868 MHz, 433 MHz, and 915 MHz, which provide radio coverage up to 2500 m.
The system is formed by end-devices and a coordinator device, located in the main controller. Use of repeaters is not supported. AgroBee-L allows up to 20 end-devices to be connected, compared to the 16 devices available for AgroBee.
There are different end-device models according to their functionality.
Soon we will incorporate the Nutri model, which is used to read 2 Nutrisens sensors; 1 AquaCheck or Drill&Drop Volumetric Water Content sensor (VWC) and temperature sensor, up to 4 levels, managed by an SDI-12 communication bus; and 1 digital sensor or counter.
It has very low power consumption. Through the integrated solar panel, energy is stored into supercapacitors or batteries, lending it a very long life.
LoRa, which stands for Long Range Modulation, is a wireless technology that uses a spread spectrum modulation called Chirp Spread Spectrum (pulsed modulated frequency). Its great advantage is that it can achieve communications over long distances (a few kilometers) and has great strength against interferences.
Using the new Wireless Module Reader (available wirelessly for AgroBee-L only), the module can be checked, operated manually, and setup in-situ, with no need for any cables.
The AgroBee-L modules can be incorporated into the Agrónic 2500, Agrónic 5500, and Agrónic Bit Con controllers.
For the provision of radio equipment, a radio coverage study is required to be carried out. This study verifies the viability of the system according to the profile of the terrain, the location of the points to be controlled, and the distance between them. The study is delivered along with the offer of controller.
