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. Thresholds are set based on the learned data, and the collars monitor activity levels. When activity levels exceeding the threshold 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.
