PROJECT NAME NPK DETECTION FROM SOIL GUIDED BY – YADAV R.V.

SOLUTION FOR NPK TEST 1)Test tube + 30 ml distilled water + 2 floc- ex tablets + dry soil. 2) Cap tube and shake it. 3) Wait for 5 minutes.

NITROGEN (N) DETECTION 1. NPK solution+ Nitrate WR CTA Tablet 2.Wait 5 minutes for color ocurrance 3.Red color form 4.Compare red color with nitrogen color chart

PHOSPHORUS (P) DETECTION 1. NPK solution + one Phosphorus Tablet. 2.Wait 5 minutes for color develop. 3. forms green color. 4.Compare green color with nitrogen color chart.

POTASSIUM(K) DETECTION 1. NPK solution + one Phosphorus Tablet 2.Wait 5 minutes for color develope 3.blue color form 4.Compare blue color with potassium color chart

NEED OF NPK IN SOIL 1.Compete growth and development. 2.Nutrients and water take up into plant. 3.Growth of fruits and seeds.

INTRODUCTIO OF NPK DETECCTION FROM SOIL In NPK detection kit color sensor TCS 230 is used. which senses color contents from soil and sends signal to AVR microcontroller. microcontroller process incoming signal and display the color contents ratio on display screen. Also indicates the absent of color contents in soil via relay switch. from that color contents we can detect the NPK ratio present in soil.

COMPONENTS USED IN PROJECT 1)Resistor 2)Capacitor 3)Filter 4)Regulator 5)Relay 6)Transistor 7)Color sensor 8)AVR microcontroller 9)Dc motors 10)5mm led

BLOCK DIAGRAM OF NPK PROJECT soil

WORKING OF PROJECT The block diagram of Project has four section namely: sensor, controller, driver and dc motor The color sensor senses the color. The controller section processes the signal coming from the sensing section block and operates as per the programming done in controller section. Three relays are interfaced to microcontroller to indicate the absent of organic material in soil. The LCD used is 16 X 2 For displaying data. i.e. it displays the detected nutrients from soil..

POWER SUPPLY DESIGN  TRANSFORMER  RECTIFIER  FILTER  REGULATOR

COLOR SENSORS

TCS230 Color Sensor is a complete color detector, including a TAOS TCS230 RGB sensor chip, white LEDs, collimator lens, and standoffs to set the optimum sensing distance. It plugs directly into the BASIC Stamp-2pe Motherboard and will also interface to any BASIC Stamp module or Propeller board using the optional DB- Expander SIP Converter. The TCS230-DB can detect and measure a nearly limitless range of visible colors. Applications include test strip reading, sorting by color, ambient light sensing and calibration, and color matching, to name just a few

AVR MICROCONTROLLER AVR  High performance, low cost 8-bit micro-controller  RISC Architecture  Low power consumption  Supports RF protocol  Supports SPI and I2C™ Master and Slave modes  10-Bit, up to 11-Channel Analog-to-Digital Converter module (A/D)
