Wireless Water

摘要

Telematics on center pivots eliminate labor, cut water use. One of the twentieth (century's top labor-sav-fing inventions - the center pivot sprinkler - is being paired up with what could be one of the twenty-first century's leading labor-saving advances - telematics. The resulting breakthrough? Irrigators not only monitor but also control pivots remotely, thereby re-placing hard-to-find hired hands. Kurt Torell invested $3,000 per pivot (he operates 16 systems) plus a communication fee to upgrade the control panels on his sprinklers to allow telematic control.
