Portable Infrasound Array

The PINA infrasonic antenna is equipped with low consumption wireless data communication between the antenna’s slave nodes and the master node and it is designed to facilitate the trasportation of the equipments and the configuration of array’s geometry in the countryside as well as in urban areas, thus offering advantages either for temporary experiments and for permanent monitoring.
