Abstract
A motion sensor unit (11) is intended to be carried by a domestic animal. The motion sensor unit (11) operates in parallel to and independently of a conventional transponder unit (1). The motion sensor unit (11) contains a motion detector (14) for measuring the activity of the animal by providing electrical pulses when the animal moves. Each hour is subdivided in a number of intervals in each one of which it is determined if the activity has exceeded a certain threshold. If it is the case, a count value is incremented. The count value is then transmitted once each hour and in addition also the count values of all the 23 previous hours. By transmitting repeatedly such information a good safety is obtained in the reception of the information signal, and this information can be used for complicated evaluation processing in a processor (7) or a supplementary personal computer (9).
