#025: Powered by Sunlight, Fenced by Software: Inside Monil's Cattle Collar

Dela

In this Coredump Session, François Baldassari and Chris Coleman are joined by Torstein Nesse, co-founder and CEO of Monil, to explore the engineering behind solar-powered livestock collars that replace physical fences with virtual boundaries. Torstein shares his path from embedded security to building a connected hardware business, and explains how Monil combines positioning, motion sensors, and sound to guide animals. The conversation covers low-power design, cellular connectivity in rural areas, offline operation, hardware selection, and the field telemetry needed to understand device behavior. They also discuss seasonal firmware updates, a four-month network debugging challenge, and how an animal-health alert helped farmers discover cattle in danger.


Key Takeaways

  • Monil’s collars use positioning, motion sensors, and sound to guide livestock within virtual boundaries.
  • Immediate feedback helps animals learn to respond to the fence and turn around.
  • The collars maintain virtual fencing offline and store telemetry until connectivity returns.
  • Continuous positioning consumes more energy than occasional electric pulses.
  • Solar charging and low-power design keep collars operating throughout the grazing season.
  • Monil chose Nordic hardware for its low-power connectivity and mature SDK, alongside a dedicated GNSS receiver.
  • Field data helped Monil develop alerts that identify animals stuck and needing rescue.
  • Larger firmware updates are scheduled outside grazing season to reduce operational risk.
  • Configurable device telemetry helps engineers investigate power consumption, fence behavior, and network failures.
  • Farmers gain better grazing management, animal-health visibility, and peace of mind.
