AgriHouse, in Berthoud, Colo., says it has developed a device that lets plants send text messages alerting growers if their water uptake is too little, too much, or just right. The sensor clips onto a plant’s leaf and uses proprietary algorithms to translate its relative level of turgidity into a reading of its internal moisture content.
