Today, the use of monitoring systems is widespread in society. However, it is not common to see them in animals.

This end-of-grade work aims to design and implement a wearable system for cows, horses, sheep and goats. Thus, the farmer can know the state of the animals and their location. Taking into account the signs and characteristics that occur in this type of animals in situations of interest, the system has several sensors: a microphone, a temperature and humidity sensor, a gyroscope, an accelerometer, an air quality sensor, a gas sensor to detect diseases and a GPS.

Thanks to the information of these sensors it is possible to know when the animal is sick, has problems walking or even the period of heat of the females and later the time of delivery.

Finally, all data is sent to the farmer to make decisions on the farm, improving the welfare of the animal and increasing its productivity.

For the development of the system, the complete hardware design and implementation was carried out, in addition to the realization of a hardware abstraction layer (HAL) for all sensors.
