Fecha de publicación: -- Fuente: WIPO "tomato" Methods and apparatus for a Precision Agriculture System are disclosed. The system includes a ground sensor (152) that collects data concerning an agricultural field (154). The ground sensor (152) includes a transmitting electrode (156) and a receiving electrode (158). These electrodes are connected to a specially-designed signal processing chip (160), a ground sensor radio (22), a ground sensor antenna (24) and a ground sensor power supply (26). A transceiver (168), which is generally remote from said ground sensor (152), includes a transceiver antenna (170), a transceiver power supply (172) and a transceiver memory (174). The transceiver (168) forwards a ground sensor response waveform (38) to a remote computer (40) via a transmission network (42), which analyzes the waveform (38) to determine information about the soil (10).
