    This research studies sensor based dairy cow estrus detection. For the study, we recorded motion and temperature data with a collar sensor. The data was used in algorithm development end evaluation. In result, we developed three different algorithms, all suitable for micro-controller based devices. All the developed algorithms succeeded in the estrus detection against a reference system. However, inactivity detection based algorithm was the mostreliable andtolerantto differentconfigurations. In conclusion, the estrus is detectable with accelerometer based sensors. However, in order to make secure conclusions, the results of this study should be verified by a successful insemination.
