Abstract
Low cost low power RF modem is very efficient in providing excellent communication at various ranges and also for low power
applications. A novel idea of motor control using PWM technique has been developed and controlled using wireless RF
transreceiver. The combination of transmitter and receiver is termed as RF transreceiver is used to exchange information in half –
duplex mode. The control of potentiometer from 0 – 5 volts controls the speed of dc motor.PIC microcontroller is used for
programming and it is downloaded to PIC microcontroller circuit used for wide range of applications the Max 232 is a driver used
to convert TTL/CMOS logic to RS 232 levels when microcontroller is serially communicated with PC. Wireless technology using
RF modem controls the motor in 30 meters range is very useful in remote and rural areas where we cannot visit directly and
frequently and monitor certain parameters.

1. INTRODUCTION
Wireless communication is the process of transferring
information from main station to two or more substations
without the intervention of electrical conductors called
wires. It is easy to move devices if not tethered by any
network cable [3]. It is also easy to construct a substation in
the hill, remote, rural areas rather than connecting using
copper wires. A radio modem transmits data many
kilometers by a wireless connection to another radio modem
over a point to point or multipoint link. More of today’s
wireless applications require battery power leads to more
power consumption. RF modules are constructed for low
power applications. Due to ease and many applications and
advantages Wireless communications can be used to control
and transmit also receive required important information
which helps in the development and also to meet the needs
and to preserve human resources from dangers [6]
.Controlling the speed of any devices is done manually in
industries and also in various sectors mainly in the field of
agriculture in some distance in centimeters.

2. MATERIALS AND METHODS
The speed of the DC motor is controlled by Pulse Width
Modulation (PWM) technique.PWM stands for pulse width
modulation. The speed control using wireless technique unit
consists of analog input, DAC board and driver circuit and
motor. The DAC design consists of the latch 74LS273, DAC
0800, and the current to voltage converting circuit using op-
amp 741.DAC 0800 is configured for bipolar output
operation. The output of the PIC will be high for certain
frequency. Using potentiometer the current can be varied
with this the motor can be controlled. Thus the varying
speed is sent through wireless by RF mode

RF MODEM, 2.4 GHz, 30 MTS RANGE
RF modem is useful for many applications [1] [2] [4] [7]
which is capable of two way wireless data transmission. The
data rate of RF module is high and used for longer data
transmissions. The RF Module is very useful and is a user
interface module. The RF module can be embedded to any
undergoing researches and PCB design. So wireless
communication system can be implemented easily [5].

PIC MICROCONTROLLER
PIC 16F877A is very useful for many versatile
performances of various tasks in the field of electronics. PIC
16F877A is precisely very cheap and easy for programming
since it has high-performance RISC CPU [1]. It has an
Operating speed DC - 20 MHz clock input and DC - 200 ns
instruction cycle.
THE PRINCIPLE OF PWM
For controlling the speed of a DC Motor, we need a variable
voltage DC power source. If we consider 12v motor and
switch on the power to it, the motor starts to speeding.
Motors do not respond immediately so it takes an adequate
time to reach full speed. If we switch the power off
sometime before the motor reaches full speed, then the
motor will start to slow down. If we continuously switch the
power low and high quick enough, the motor will not settle
immediately. It will run at some speed part way between
zero and full speed. A PWM controller has the same
principle. It switches the motor from series of pulses. It
modulates the width of the pulses .So Pulse Width
Modulation is used for motor control.
Speed Control of DC Motor Using PWM
DC motors are mainly used in industrial applications and
agricultural aspects etc. In this regard the control of the
distance in wide distances is very much important. In this
scenario motor plays a major role [8]. Therefore we need to
control the motor for our needs. Our aim is to control the
speed of the DC motor using wireless communication. The
speed of DC motor is controlled by voltage, armature
resistance and flux etc. But in this project we control the
speed of the DC motor by Pulse Width Modulation (PWM)
technique. The voltage is controlled by the duty cycle of the
PWM signal [9]. The duty cycle is referred to as [10]
Duty cycle = X 100 (1)
From this method it can be obtained by smooth speed
variation without reducing the starting torque of the motor.
PWM techniques also eliminate harmonics. The DAC
output is given to inverting terminal of IC 741 for
amplification and output is given to driver IC ULN 2003 for
controlling the motor.](https://image.slidesharecdn.com/designdevelopmentandimplementationofnovelidea-160922133746/85/Design-development-and-implementation-of-novel-idea-2-320.jpg)

CONCLUSION
The essential aim of this project is to design a motor
control system which enables to monitor in an industry also
agricultural aspects by using RF modem and display. The
components used in the circuits are readily available. The
PCB layouts are designed as supporting circuits and fully
tested with full functionality in working environment. The
wireless motor control is essentially a design and
implementation project of wireless technology. Finally we
are very well succeeded in controlling the motor which is
very useful in the places where we can preserve the human
resources from risky environment.
The project is very simple, and this simplicity leads to many
useful, reliable and helpful for the society is the satisfactory
minds of any individual.
FUTURE SCOPE
RF for motor control can also be implemented in
SOC(System On Chip )for even more sophistication and
very useful for the society[2].SOC technology is the
packaging of all the obligatory electronic circuits and parts
of a system on a single integrated circuit(IC)generally
known as micro chip.
