The document outlines a project aimed at designing an infrared remote control switch for operating home or industrial appliances, enhancing efficiency and saving time. The circuit uses components such as an IR receiver, transistors, and a counter IC, functioning within a range of 5-10 meters, and can be controlled using any TV remote. Key advantages of the system include portability, simplicity in construction, and low power consumption.

2. iNTRODUCTiON
The aim of this project is to design a circuit such
that one can control home or industrial
appliances using the help of remote.
Using remote to control appliances reduces
human efforts without compromising on
efficiency. It also saves time.
This circuit can be operated upto a distance of 5-
10 metres of Range.

3. REQUIREMENTS
• 5V Regulator 7805 (IC)
• BC547 (NPN Transistor)
• BC558 (PNP Transistor)
• RELAY
• TSOP 1738 (IR Remote Control receiver)
• RESISTANCES
• CAPACITORS(0.1 mF,100mF)
• CD 4017 (COUNTER IC)

4. THE CIRCUIT

5. WORKING
 Home appliance is controlled either by pressing any key on the
remote.
 The circuit works on regulated 5V which is obtained from regulated
by IC7805.
 The TV/DVD remote controller produces 38kHz frequency.
 IR RECEIVER MODULE: The IR receiver module operates at this
frequency(38kHz).
 The relay triggers IC CD4017, which is wired in a bi-stable mode to
control the home appliance connected at the contacts of Relay.

6.  CD4017 IC:CD4017BM/CD4017BC is a 5-stage
divide-by-10 Johnson counter with 10 decoded
outputs and a carry out bit.
 The 10 decoded outputs are normally in the logical
``0'' state and go to the logical ``1'' state only at
their respective time slot.
 IR receiver module (TSOP1738) :
At normal condition, when IR rays are not incident
on TSOP1738, its output at pin 3 remains high.
When any TV remote key is pressed, IR rays fall on
the TSOP1738 and its output goes low.

7. ACTUAL CIRCUIT

8.  The IR detector is used in this project is tuned to detect IR
radiation pulsed at a specified frequency only.
 This is the frequency at which the standard TV remotes work,
hence a TV remote also can be used instead of the IR LED
based remote.
 Since we are not modulating any additional information with
the IR pulses the detector can be used to operate only one
switch..
 The IR detector is tuned not to respond to stray IR coming
from natural light or any other source like tube light etc in your
home.
 To transmit the radiation we use IR led in remote control.

9. APPLICATIONS
 This system can be used in industrial applications.
 This system reduces human efforts and makes life a bit easy
without compromising on the efficiency of appliances.
 Using this system one can also save time.
ADVANTAGES
 Portable and easy to use.
 Simple in construction.
 Easy to maintain and repair.
 Efficient and low cost design.
 Low power consumption.
