The TBS12 is best described as an SDI-12 to LoRa WAN Bridge: it allows SDI-12 sensors to be connected to a LoRa WAN network. As SDI-12 is widely used in the agriculture and environmental sectors, this makes it easy for companies to bring their existing sensor investment in to the LoRa WAN ecospace..




The TBS12 is available in a number of different versions:
  TBS12S: with solar power and rechargeable battery
  TBS12B: with power from a set of 3 off C sized alkaline cells
  OTTO-LO: a LoRa WAN head designed to fit inside  top of an above ground
   Otto soil moisture probe




The TBS12S is a solar powered version of the TBS12 which is built around a polycarbonate case with integrated solar panel. A 7 pin M14 connector on the bottom of the case connects to the SDI-12 sensors.

The TBS12S is ideal for straightforward monitoring projects which do not require pulse or analogue sensors. The case is fitted with a breather vent to prevent moisture buildup. A post mounting bracket allows for easy installation  in the field




The TBS12B is intended for use in applications where a solar panel is not a viable option. This may be for indoor locations such as greenhouses or for tree crops where the canopy blocks out the sun.

The TBS12B is built into the same powder-coated aluminium case as the TBSL1. Rather than use expensive Lithium batteries, the TBSL1 relies on a set of 3 off D sized  Alkaline batteries, which are both cheap and readily available. To further boost the product’s green credentials you can even power it from a set of long life rechargeable cells, which are simply swapped out for charged cells as the battery voltage starts to dip.

Like the TBS12S, the sensors connect via a 7 pin M14 connector.




The TBS12P is available as a PCB and can be integrated into a variety of cases. The TBS12P has two pulse inputs which can be connected to flow meters or  rain gauges. The unit can be programmed with the number of units per pulse and then reports the outputs in the corresponding engineering unit (lites, mm etc.)For flow monitoring applications, the TBS12P can report both the flow in the logging period and the totaliser value at the end of the period.

The TBS12P has been designed around the use of a lithium battery as a power source, but this can easily be swapped for alkaline cells or  a plugpack or solar supply.




The Otto LO is a telemetry enabled version of the Otto Soil Moisture probe. In this configuration the standard “T” shaped PCB at the top of the probe is replaced with a TBS12 LoRa WAN board. An antenna socket is fitted in place of the probe cable.

The Otto-LO is powered via an AA sized single use Lithium battery.

The Otto-Lo is the ideal choice for monitoring in shallow rooted vegetables and row crops. It is quick to install and commission and can be easily removed and relocated come harvest.
