Each Ushimiru collar observes the movements of the cow it is attached to. Whether it’s dairy cattle, beef cattle, living in mountainous areas, or on flat pastures, the collar learns the cow's behavior. Based on this learned data, the collar monitors for signs of estrus. When such signs are detected, an alert is sent to the registered email address. Additionally, the Ushimiru app displays the proportions of grazing, lying down, ruminating, and walking for each cow.
