AUTOMATED SOIL TESTING DEVICE

FIELD OF INVENTION

[0001] Present invention is related to the field of 'AGRICULTURAL ELECTRONICS'. A device named as 'Automated Soil Testing Device (ASTD) is developed and built for implementation of soil testing in agricultural lands.

BACKGROUND OF INVENTION

[0002] For good forming fertility of soil is important. The fertility depends upon 'npk' (Nitrogen Phosphorous Potassium) and 'pH' (potenzy hydrogen) values.

[0003] Soil testing labs are located in cities and district head quarters and farmers should take the pain of visiting such testing laboratories.

[0004] At present a soil testing kit is available, which functions on conventional way.

[0005] Definite mechanism to test the soil is not available.

[0006] The existing mechanism is not user friendly and consumes time.

BRIEF DESCRIPTION OF THE DRAWINGS

[0007] Invention described herein is illustrated by way of example and not by way of limitation in the accompanying figures. For simplicity and clarity of illustrations, elements related in the figures are not necessarily drawn to scale. For example, the dimensions some elements may be exaggerated relative to other elements for clarity. Further, wherever considered appropriate, reference labels have been repeated among the figures to indicate corresponding or analogous elements.

[0008] Drawings are used to illustrate the 'Automated Soil Testing Device' applicable in agriculture.

[0009] Fig.l represents the flow diagram of complete hardware part of the prototype model of 'Automated Soil Testing Device' (2000) [here onwards called as ASTD (2000)]. consisting of a Soil Sample (1000) Sensor (2001), Signal conditioning (2002), it is an instrumentation amplifier, ADC (2003), I/O Interface (2004), Microcontroller (2005), wireless Trans - receiver (2006) and LCD display (2007).

[0010] Fig. 2 shows the prototype model of ASTD (2000) consisting of electrodes (2008) fixed to a panel (2009) with LCD display (2007) and a key pad (2010) dipped in soil mixture called soil sample (1000).

DETAILED DESCRIPTION

[0011] Following is the description of the device called, 'Automated Soil Testing Device' ASTD (2000). Numerous specific details such as logic implementations, resource partitioning/ sharing /duplication implementations, types and interrelationships of system components and logic partitioning /integration choices are set fourth in order to provide a more clear understanding of the present invention. It will be appreciated, however, by one skilled in the art that the invention may be practiced without such specific details. In other instances, constructional details and other such details have not been shown in detail in order to obscure the invention. Those of ordinary skill in the art, with the included descriptions, will be able to implement appropriate functionally without undue experimentation.

CONCEPT OF AUTOMATED SOIL TESTING SYSTEM FOR AGRICULTURE

[0012] The basic concept is that the voltage depends upon fertility of soil which in turn depends upon 'npk' and 'pH' values.

[0013] The ion current is converted to electron current.

[0014] The soil fertility is tested by means chemical process.

CONSTRUCTION OF AUTOMATED SOIL TESTING SYSTEM FOR AGRICULTURE

[0015] ASTD (2000) consists of electrodes (2008) fixed to a panel (2009) with LCD display (2007) and a key pad (2010). The electrodes (2008) are dipped in a mixture of soil called soil sample (1000).

[0016] The ASTD (2000) is a portable device and it can be used either in the laboratories or directly at the selected spot in the indentified agriculture land.

[0017] Fig. 2 shows the prototype model of ASTD (2000) consisting of electrodes (2008) fixed to a panel (2009) with LCD display (2007) and a key pad (2010) dipped soil mixture called soil sample (1000).
WORKING OF AUTOMATED SOIL TESTING SYSTEM FOR AGRICULTURE

[0018] A sample of the soil, which is to be tested is mixed distilled water, which is called the soil sample (1000).

[0019] The electrodes (2007) of ASTD (2000) are dipped in the soil sampler (2005).

[0020] The digital display (2007) displays the necessary data such as 'npk' and 'pH' values and thus suggests the suitable crop and the fertilizer to be used as per the chart available in agriculture department.

[0021] ASTD (2000) automatically transmits the necessary data such as 'npk' and 'pH' values by means of Trans - receiver (2006) to the experts or such designated authority in the agriculture department for further analysis and suggestions.

[0022] ASTD (2000) employs GSM technology.

SPECIAL FEATURES
[0023] ASTD (2000) is a portable device and thus can be used either in the laboratory or at the selected spot in the identified agriculture land.

[0024] ASTD (2000) gives direct display the necessary data on LCD display (2007) so that a lame person/farmer or uneducated/untrained person/farmer can easily use it without the presence of any operator and decide the type of the crop to be grown or the suitable fertilizer, which can be used.

[0025] ASTD (2000) transmits the data automatically to the experts or the designated authority for further analysis.

[0026] ASTD (2000) employs GSM technology.

[0027] ASTD (2000) is a simple and user friendly device.

[0028] The cost of ASTD (2000) is small and easily affordable by a poor man.
