Cows are stoic animals. They hide injuries to avoid rejection from the rest of the herd. This makes it harder for farmers to notice too, and that delays treatment for the animal and prolongs its suffering.

Halter's solar-powered collar has sensors which detect subtle changes in animal behavior and movements.

Problem definition

Our user problem could be summed up as follows:

Animal injuries and illness can go undiscovered for weeks, delaying medical treatment. This can result in prolonged animal suffering, higher likelihood of mortality, and higher cost to the farmer.


Our team made several important realizations.

  • Collar sensor data - Halter's collars continuously collect valuable information from the collars
  • Machine learning - Sensor data can be analyzed in real time to identify possible illness or injury
  • Farmer records - Farmers record animal health events in notebooks, on whiteboards, and in WhatsApp messages

Gain confidence

Ideate + Iterate

Initially, we released a product which displayed the hour-by-hour activity level of each animal.

This proved to be too granular, which made it hard to identify clear changes from day to day.

After a first release of the health timeline, we iterated. In the next release, we moved toward showing activity data in a day-by-day breakdown.

This made it much clearer when a single animal's behavior changed significantly from one day to the next.
