Career point university Presentation

on Smart Measurement of soil by Robot GUIDED BY SUBMITTED BYMr. Somesh Chaturvedi Deepak soni(k10709) (Assist. Prof. EE dept.) Hariom gujar(k11350) Mohit Navriya(k10778) 

INTRODUCTION In this project we interface the soil

parameter like moisture, with embedded programming. By this robot we can easily measure the presence of water or moisture in the soil of the agriculture land. This robot is very useful for farmers, because it will automatically display the moisture of the land/soil.

COMPONENTS USED

Micro-controller Atmega16 7805 Voltage regulator Soil sensor LCD display Relay chess LED Resister, capacitor, transistor, diode

Microcontoller ATmega 16

This microcontroller is used to generate all the required logic for this circuit.

ATmega16 is an 8-bit high performance microcontroller of Atmel’s Mega  family with low power consumption. Atmega16 is based on enhanced RISC (Reduced Instruction Set Computing, Know more about architecture with 131 powerful instructions. Most of the instructions execute in one machine cycle. Atmega16 can work on a maximum frequency of 16MHz. 

conti….  ATmega16 has 16 KB programmable flash

memory, static RAM of 1 KB and EEPROM of 512 Bytes. The endurance cycle of flash memory and EEPROM is 10,000 and 100,000, respectively.

 ATmega16 is a 40 pin microcontroller. There are 32 I/O (input/output) lines which are divided into four 8-bit ports designated as PORTA, PORTB, PORTC and PORTD.

  ATmega16 has various in-built peripherals like

USART, ADC, Analog Comparator, SPI, JTAG etc. Each I/O pin has an alternative task related to in-built peripherals. The following table shows the pin description of ATmega16.

7805 Voltage regulator

7805 is a voltage regulator integrated circuit. It is a member of 78xx series of fixed linear voltage regulator ICs. The voltage source in a circuit may have fluctuations and would not give the fixed voltage output. The voltage regulator IC maintains the output voltage at a constant value. The xx in 78xx indicates the fixed output voltage it is designed to provide. 7805 provides +5V regulated power supply. Capacitors of suitable values can be connected at input and output pins depending upon the respective voltage levels.

Soil moisture sensor Soil moisture sensor it is a resistive

sensor. It’s made of two exposed electrodes and uses the fact that more water contents, the lower the resistance b/w the two electrodes. the resistance can be measured by simple voltage divider and a analog pin.
