Embodiment Construction

[0013] For clarity, this disclosure will be described as applied to a planter unit. It should be noted, however, that the present disclosure may also find application in various planting and / or soil preparation applications including, but not limited to, tilling, seeding, and the like. refer to Figure 1 to Figure 2B , shows a sensing system 100 for determining soil properties in real time, according to an embodiment. In an embodiment, sensing system 100 may include at least one sensor 106 disposed on support structure 102 (at Figure 2A middle) and is operatively coupled to the measurement unit 108. The support structure 102 may be adapted to be coupled to an agricultural implement (such as Figure 4A The planter unit 400 in ) and is arranged so that as the implement moves in the field, the support structure 102 rotationally engages or penetrates the surrounding soil. In some embodiments, support structure 102 may comprise a disc or another wheel-like structure (see, eg, ...

Abstract

Disclosed herein is a sensing system that obtains, in real time, the gradient of soil properties as a function of soil depth. The sensing system includes a support structure coupled to an agricultural implement and rotatable about an axis of rotation relative to a frame of the agricultural implement. The sensor is disposed on the surface of the support structure and is configured to generate an output signal indicative of the measured soil property based on a sensed change in capacitance corresponding to a measured soil sample interacting with the sensor. Changes in dielectric properties. The measurement unit is coupled to at least one sensor and processes an output signal generated by the at least one sensor in real time for display on the user interface, the gradient profile of the soil property as a function of one or more depths.

Description

technical field [0001] The present disclosure generally relates to sensing systems that utilize real-time data measurements to obtain gradient profiles of soil properties. Background technique [0002] In agricultural applications, when farmers are performing tasks such as planting or tilling, they often want to know some properties of the soil in real time. These properties may include humidity, compaction, temperature and groove depth; each of these properties is extremely important in ensuring optimal yield. For example, conditions of insufficient humidity or temperature can adversely affect the production of crops, resulting in reduced yields. [0003] However, disadvantages of some prior art methods include high cost or low sensor resolution. Therefore, there is a need in the art for a sensor system that provides high resolution at a relatively low cost. Contents of the invention [0004] According to an embodiment, there is provided a sensing system for obtaining ...
