Claim Text:
1. An extendable wireless soil measurement apparatus, comprising: a top head, disposed above a soil surface for transmitting data to a data station through a wireless means; and a plurality of sensors, disposed under soil for sensing soil conditions, generating soil data representing the sensed soil conditions, and transmitting generated soil conditions to the top head, the plurality of sensors able to be assembled into a pole; wherein each of the plurality of sensors further comprising: a sensor unit for sensing a soil condition and generating soil data representing the sensed soil condition; a circuit module connected to the sensor unit for transmitting generated soil data to the top head a sensor housing for housing the sensor unit and the circuit module; and an engaging element for engaging two sensors in a head-to-tail manner to form a pole, wherein the apparatus further comprises at least a connector, the connector being disposed between sensors or between the sensor and the top head to adjust the pole length and the depth of the sensors when the apparatus is buried under soil, and the connector further comprises a metal line for reducing wireless transmission loss through the connector.
