LoRaWAN Pulse Counter - TBS12PC


LoRaWAN Pulse Counter - TBS12PC


The TBS12PC LoRaWAN pulse counter module brings LoRa wireless connectivity to pulse sensors, empowering the long-range capability of LoRa along with flexible configuration. It is available in 2 variants depending on the targeted application: TBS12PC-RG for rain gauges or flow meters monitoring and TBS12PC-FS for float switches monitoring.

The module embeds a low power LoRaWAN 1.02 certified modem, with dual antennas connectors to operate on low (434MHz/470MHz) and high (868MHz/915MHz) ISM bands.

It offers low current consumption, small footprint and easy integration with available rain gauges and float switches on the market.


  • LoRaWAN 1.02 Class A
  • Supports all regional bands as defined in LoRaWAN 1.02 regional parameters specification.
  • Flexible LoRaWAN configuration:
  • ABP / OTAA
  • Confirmed / Unconfirmed messages
  • Configurable LoRaWAN identifiers, ciphering keys, frequencies and data rates
  • Easy configuration with PC tool through TBS12PC’s UART port
  • 2 pulse inputs
  • Configurable measurements and transmission intervals.
  • Configurable transmission delay to allow to stagger multiple units and limit collisions.
  • Common HW with 2 software variants:
    • Rain gauge and flow meter applications (reports the amount of rain or flow totalizer)
    • Float switch monitoring application (configurable alarm, reports the float switch state’s change and the duration for each state)
