AgroBee-L SDI-12 System
Very low consumption radio modules and integrated parts of the AgroBee-L system
for reading up to 4 (VWC: Volumetric Water Content) soil water content, Temperatu-
re, and EC (electric conductivity) or VIC (Volumetric Ion Content) tri-sensors through
an SDI-12 communication bus that allows you to connect different sensors to the same
point, since each one of them has a cirtain direction that distinguishes it from the rest.

  • Page 2: Technical Characteristics

    This module is powered by a 1.05 W solar panel + supercapacitors, already incorporated into the machine (no need to replace batteries). The number of sensors a module uses, as well as their type, can be configured using a Module Reader of the module itself, or from the controller to which said module is associated.

  • Page 4: Installation

    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.
  • Page 5 INSTALLATION MÓDULOS The AgroBee-L modules have the antenna integrated into the Module module, so they are installed on top of a post. For good radio communication, it is very important to place the modules in areas free of vegetation, walls, and metal structures. The minimum recommended height to place the module is 4.5 Post metres from the ground.

  • Page 6: Inputs And Outputs

    Inputs and Outputs DIGITAL INPUTS There is 1 digital input in an AgroBee-L SDI-12 module, which can function either as a digital input or counter/rain gauge input. When the input is connected to a counter, the minimum time between pulses must be 0.1 seconds. Maximum allowed distance between AgroBee-L module and a digital sensor or meter is 50m.
  • Page 7 Settings For any AgroBee-L module to enter the correct operating mode, you must have an Agrónic con- troller (Agrónic 2500, Agrónic 4500, Agrónic 5500 and Agrónic Bit Con) with the AgroBee-L option installed, which includes the internal coordinator and an antenna with 10 metres of cable.

In addition to the tempera- ture value [°C] and EC [µS/cm] (the AgroBee-L module changes the reading to [mS/cm]=[dS/m]), the sensor gives you a RAW value, which the SDI-12 module transforms into VWC [%] (Volumetric Water Content) with the following expression: VWC [%] = a*RAW3 + b*RAW2 + c*RAW + d, and according to the type of terrain: i.Mineral:...
  • Page 23 Campbell CS650 In addition to the temperature value [°C] and EC [mS/cm], the sensor directly gives you the value of VWC [%] (Volumetric Water Content). The sensor itself uses the following Topp equation to calculate the VWC: VWC [%] = -5,3*10-2+2,92*10-2Ka-5,5*10-4Ka2+4,3*10-6Ka3, where Ka is the average dielectric constant.
  • Page 24 Stevens Hydraprobe-II Important: For this sensor, the AgroBee-L SDI-12 module only delivers the first three values obtained through the default SDI-12 command “aM!”, that is, the tempera- ture value [°C], EC [mS/cm], and the value of VWC [%] (Volumetric Water Content). The calculated value of the VWC is valid for any clay-type terrain.
  • Page 25 AquaCheck-4 / AquaCheck-8 This sensor delivers a value between 0 and 100, which repre- sents the VWC (Volumetric Water Content). In order to obtain the desired VWC value, the relevant equation must be applied according to the type of terrain, which is already done internally by the AgroBee-L module: i.Mineral: iv.Mud-Loam:...
  • Page 26 Sentek Drill& Drop Moisture-Temperature / Sentek Drill&Drop TriScan This sensor delivers the VWC (Volumetric Water Content), the volumetric ion content (VIC, only for TriScan) and tempe- rature. The temperature values obtained [°C], VIC[] and VWC [%] are converted, by the module itself, to the standard 4-20 mA (800-4000 mV) format, so you must select the suitable data format in the controller in question according to the type of sensor selected.
  • Page 27 Apogee NDVI/PRI These sensors should be installed in pairs: hemispheric sensor (pointing up) and field-stop sensor (pointing towards the plant). The value of PRI/NDVI is calculated based on the measurements of both sensors, and the module itself delivers the processed PRI/NDVI value to the programmer (type PRI/NDVI).
  • Page 28 Meter Group Teros-21 This sensor delivers the Agual Potential in Soil (kPa) and soil tempera- ture [ºC]. The values obtained from temperature [° C], and Potential [%] are converted, by the module itself, to standard 4-20 mA (800-4000 mV) format, so that in the programmer in question the format must be selected of suitable data according to the type of sensor selected.
  • Page 29 EnviroPro This sensor provides the soil water content index (VWC), Electrical Conductivity (EC) and temperature. The values obtained for temperature[°C], EC[dS/m] and VWC [%] are converted, by the module itself, to the standard format 4-20 mA (800-4000 mV), so that in the controller in question, you must select the ideal data format according to the type of sensor selected.
