To improve efficiency, dairy farmers monitor the inputs and outputs of their cows based on data collected by sensors. Currently the main sources for this data are the given food and information about the milk (composition and volume). This data helps the farmer make better decisions regarding animal welfare and feeding practices. However, one of the outputs of the cow is currently not monitored, namely the manure. A system that monitors herd manure data in a barn using sensor technology was proposed. It should give the farmer interpreted feedback enabling him to have more control over farm efficiency both financially and ecologically.
