Battery powered LoRaWAN RTU

TBS12B

Battery powered LoRaWAN RTU for SDI-12 sensors

TBS12B is a battery powered outdoor RTU fully LoRaWAN 1.02 compliant. It has been designed to cope with applications where SDI-12 maximum range is a limitation by leveraging the long range capability of LoRa. TBS12B is delivered within its IP67 rated aluminium die cast housing along with a fixture to tie it to a pole. Its connector allows plugging directly one SDI-12 sensor or a junction box would multiple SDI-12 sensors need to be locally deployed.

The embedded LoRa modem supports both low (433/470MHz) and high (868/915MHz) LoRa radio bands, which makes TBS12B suitable to be used anywhere without having to replace the RF board.

With a limiting threshold of +11dBm and a flat frequency response from 9 kHz to 600 MHz, the TBS12B limiter can be used as protective device for the complete range of conducted noise measurements and in many other applications.

   ▪ Compatible with SDI-12 v1.3 compliant sensors

   ▪ Supports all regional bands as defined in LoRaWAN 1.02 regional parameters specification.

   ▪ Flexible LoRaWAN settings:

   ▪ ABP / OTAA

   ▪ ACK / REPEAT features

   ▪ Configurable frequencies and data rates

   ▪ EUI and ciphering keys

   ▪ PC application to configure the platform (UART)

   ▪ Configurable measurement and transmission intervals; timing alignment and time zone support

   ▪ Up to 16 SDI-12 commands can be programmed

   ▪ Batteries: 3*1.5V DCELL

   ▪ Low quiescent current: 5-7µA

   ▪ Operating temperature: -40; +85 °C

TBS12B is deployed as a unique node into a typical LoRaWAN network architecture, sending its packets to the gateway that relays them to the LoRaWAN server over a TCP/IP connection :
