INTRODUCTION
Drip irrigation system based on RFID. In this system remade unit will sense the soil moisture and then it will send that soil moisture to controller by using the rfid communication protocol. Controller sense the moisture then it will decide whether motor will on or off by using the set point that will already given to controller by using the keyboard.Lcd will show continuously the soil moisture ....etc

smart irrigation system using at89s52 pdf

Abstract

In this world irrigation of various crops in different regions are indeed playing very dominant and challenging role. Crops yielding is very much dependent on various factors such as ambient temperature, pH value of soil, water level in the field etc. In this research paper the main intention is to improve the yielding of crops by controlling the above parameters using Sensors, Global System for Mobile (GSM) module and with the help of an 8 bit ATMEL microcontroller AT89s52. Another importan ....etc

pwm based on dc motor control using at89s52 microcontroller

A pulse width modulator (PWM) is a device that may be used as an efficient DC motor speed controller or light dimmer. This project is a versatile device that can control DC devices which draw up to a few amps of current. The circuit may be used in either 12 or 24 Volt systems with only a few minor wiring changes. This device has been used to control the speed of the DC motor and to control brightness of an automotive tail lamp. A PWM circuit works by making a square wave with a variab ....etc
