Abstract

The device for determining movements of an animal comprises a housing, at least one G-sensor for detecting movements of the housing and for generating signals representing the detected movements. The device further comprises an electronic circuit connected to the G-sensor for processing signals received from the G-sensor so as to obtain processing results, transmitting means connected to the electronic circuit for transmitting the processing results and a power supply for at least feeding energy to the G-sensor and the electronic circuit wherein the G-sensor, the electronic circuit, the transmitter means and the power supply are located within the housing. The electronic circuit may be arranged for switching the G-sensor on and off according to a predetermined time pattern so as to save energy.
