About the job

Looking for a LoRa wireless connection specialist who can help us to implement data transmission between a daisy chain of sensors and a gateway device.


  • Create a day chain of small, self-operating, solar-powered sensors (up to 100 or more per one daisy chain if possible)
  • Each sensor sends ~10 bytes of data periodically, every ~1-3 minutes
  • Distance between the sensors will not exceed 1 mile in a wildland area, will be smaller if needed in hilly areas blocking the transmission
  • As low power consumption as possible
  • LoRa protocol is envisioned with Semtech SX1276/7/8/9 or HopeRF RFM95W chips.


We are bringing radically early detection of fires to the outdoor environment.
