I think there's more to this project than you realize. Although that IR receiver circuit board looks very simple, the little chip on the back is a microcontroller (Like a Microchip PIC12F675) that contains several hundred lines of code. Remember that this circuit is a "self learning" remote. Each company that makes IR remote control system has their own proprietary way of encoding the signals that they send, and a single button press on the IR transmitter usually results in transmission of start bits, a stream of data, stop bits, possibly a CRC checksum, and other data. Look here: http://www.righto.com/2010/03/understanding-sony-ir-remote-codes-lirc.html for more information about the Sony Remote control protocol and the Arduino library. If you want to "roll your own" then the information given in Mike Anderson's post is what you need. -Rick

Adnan....I appreciate you wanting to do this yourself but it could turn out bigger than Ben Hur, depending on what type of remote you want to use. Also you are turning on and off lethal voltages (mains 110/220V AC) and if you don't know exactly what you are doing this is to be avoided!You can buy pretty cheaply (~30 US$) a set of three switch modules and a remote control like this:https://www.kogan.com/au/buy/doss-mains-outlet-remote-controller-doss/
The remote is RF, not infrared, so the controllers can be behind chairs, etc and still work.I have a disabled wife and have a set like this in my lounge, she can easily turn on/off all the standard lamps with this, but it would be very difficult otherwise.As I say I do appreciate your desire to do this yourself but why reinvent the wheel, expecially when the solution is so cheap?Best // David

Thanks David.Bro I'm enrolled in Electrical Engineering in 3rd Semester. I have been given the project from university to design circuit to light up a 220v bulb using ir sensor...... Provide me the circuit diagram..... circuitry should be simple. >>>>> ir diode, photodiode, relay, transistor and some kind of ic that should relate the ir section to transistor and relay.........

Adnan, ok, I see where you are coming from. Here is a circuit you can use as a starting pointhttp://www.electronicshub.org/ir-remote-control-switch/
But let me give you a few pointers to help you along the way- you can just detect IR from your LED but if is is just steady IR, your receiver can get fooled by the sun or light bulbs, etc- so usually you would have a chain of IR pulses at a certain frequency (here 5 KHz) and if possible make your receiver only respond to that frequency- if you really want to get secure, you can get ICs like HT12E (encoder) and HT12D (Decoder) which need a certain code of pulses to work, you get even more complex one which change the code as well, but you needn't worry about that for your project.Make sure you don't just build a circuit, make sure you understand how it works. If I was examining you, I'd want a detailed description! :-)Good luck and let us know how you get on
Cheers // David

Topic summary

✨ The discussion focuses on designing a simple remote control system for home appliances such as bulbs and fans using an IR sensor and Arduino or basic electronic components. The user intends to use a common TV or AC remote as the IR transmitter without purchasing a dedicated IR remote. Key points include the complexity of decoding IR signals due to proprietary encoding protocols involving start bits, data streams, and checksums. A microcontroller or dedicated IC is typically required to interpret these signals. Suggested components for a basic circuit include an IR photodiode or IR receiver module, transistor, relay, and possibly encoder/decoder ICs like HT12E and HT12D for secure communication. The importance of using modulated IR signals (e.g., 5 kHz pulses) to avoid interference from ambient light is emphasized. Reference circuits and tutorials such as those on electronicshub.org were recommended for practical implementation. Safety concerns regarding switching mains voltage (110/220V AC) were also highlighted, advising caution. Alternative solutions like RF remote-controlled switch modules were mentioned but the user prefers a DIY IR-based approach for an academic project.

How to Make Remote Control Home Appliances Using IR Sensor and Arduino?

FAQ

TL;DR: Expect “several hundred lines of code” and a microcontroller because consumer IR remotes use a “proprietary way of encoding.” Build it with an Arduino, an IR receiver, a driver transistor, and a relay to switch 110/220 V safely. [Elektroda, Rick Curl, post #21678038]

Why it matters: This FAQ shows students and hobbyists how to make a TV‑remote‑controlled mains switch safely and quickly, or pick a ready-made alternative.

Quick Facts

Scope: On/off control of bulb/fan using a TV/AC IR remote, Arduino, IR receiver, transistor, and relay. [Elektroda, Adnan Ali Saifi, post #21678040]
Safety: Mains 110/220 V AC is lethal—use proper isolation and relays/enclosures. [Elektroda, David Ashton, post #21678039]
Signaling: Example student circuit uses burst modulation around ~5 kHz to avoid ambient light; protocols vary. [Elektroda, David Ashton, post #21678041]
Parts option: HT12E/HT12D encoder/decoder pair avoids protocol decoding complexity. [Elektroda, David Ashton, post #21678041]
Time-saver: Off‑the‑shelf RF outlet kits cost ~US$30 and work through obstacles. [Elektroda, David Ashton, post #21678039]

What’s the exact goal this thread tackles?

Switch a 220 V light (and similar loads like a fan) on/off using an infrared sensor and a common TV/AC remote, built as a simple student project. [Elektroda, Adnan Ali Saifi, post #21678040]

Can I use a TV/AC remote directly with Arduino to toggle a relay?

Yes. Use an IR receiver module to decode the remote and have Arduino drive a transistor that energizes a relay. Remember, “each company…has their own proprietary way of encoding,” so you must decode and map buttons first. [Elektroda, Rick Curl, post #21678038]

Do I really need a microcontroller, or can I keep it all‑hardware?

You can skip protocol decoding by using an HT12E (encoder) at the transmitter and HT12D (decoder) at the receiver, then drive the relay. This simplifies logic but ties you to your own remote, not a TV remote. [Elektroda, David Ashton, post #21678041]

What IR modulation should I plan for in a simple build?

To reject ambient light, modulate your IR LED in bursts at a chosen frequency; an example student circuit used about 5 kHz. Remote controls use different schemes, so treat 5 kHz as a didactic example, not a universal setting. [Elektroda, David Ashton, post #21678041]

How do I stay safe when switching mains (110/220 V AC)?

Use a rated relay or SSR with proper creepage/clearance, an enclosed mains section, and strain relief. Keep low‑voltage and mains grounds isolated. If unsure, use a certified plug‑in module instead. Lethal voltages demand caution. [Elektroda, David Ashton, post #21678039]

Which Arduino library should I use to decode common TV remotes?

Use the IRremote library. It supports many protocols (NEC, Sony, Samsung, RC5/RC6, JVC, Panasonic, LG, and more), making button capture and mapping straightforward. [IRremote - Arduino Libraries]

Give me the 3 basic steps to build it with Arduino.

Capture IR codes from your TV/AC remote using an IR receiver and the IRremote example to identify button values.
Map chosen codes in your sketch to toggle a GPIO output state variable.
Drive a transistor + flyback diode to energize a relay module that switches the lamp. [Understanding Sony IR remote codes, LIRC files, and the Arduino library]

What if sunlight or room lights cause false triggers?

Ambient IR can fool simple receivers. Use a modulated IR link and a demodulating receiver tuned to your burst frequency, add shielding, and position the sensor away from direct light. [Elektroda, David Ashton, post #21678041]

Is there a quick alternative if my deadline is near?

Yes. Buy a multi‑outlet RF remote kit. Around US$30 gets several plug‑in modules and a handheld remote that works through furniture and walls. [Elektroda, David Ashton, post #21678039]

What parts list should I start with for the student build?

Typical: Arduino (e.g., Nano/Uno), IR receiver module, IR LED (for learning/feedback), NPN transistor + base resistor, flyback diode, relay or SSR module, and a fused enclosure for mains wiring. [Elektroda, David Ashton, post #21678041]

What is Arduino Nano?

A compact, breadboard‑friendly Arduino board originally based on the ATmega328P (16 MHz, 32 KB flash). It offers Uno‑like functionality in a smaller form factor for embedded projects. [Arduino Nano]

What is Tuya?

Tuya (Tuya Smart) is a Chinese IoT platform‑as‑a‑service provider that powers many branded smart‑home devices and ecosystems worldwide. [Tuya Inc.]

What is CAN bus?

CAN bus is a differential, multi‑master serial network used in vehicles and industry, supporting robust, prioritized messaging up to 1 Mbit/s in Classical CAN. [CAN bus]

What is OpenBeken?

OpenBeken is open‑source firmware that replaces vendor firmware on Tuya‑type modules (e.g., BK7231), offering Tasmota‑like configuration, MQTT, and Home Assistant integration. [GitHub - openshwprojects/OpenBK7231T_App]
