The dominant remote-control technology in home-theater applications is infrared (IR). Infrared light is also known as plain-old "heat." The basic premise at work in an IR remote control is the use of light to carry signals between a remote control and the device it's directing. Infrared light is in the invisible portion of the electromagnetic spectrum.
infrared remote controller for home appliances
An IR remote control (the transmitter) sends out pulses of infrared light that represent specific binary codes. These binary codes correspond to commands, such as Power On/Off and Volume Up. The IR receiver in the TV, stereo or other device decodes the pulses of light into the binary data (ones and zeroes) that the device's microprocessor can understand. The microprocessor then carries out the corresponding command.
The universal infrared remote control is an example of a helpful device for daily use. You can remotely control household appliances from the smartphone screen by turning such a remote control into an Internet of Things device. For example, turn on the air conditioner in advance when returning home on a hot summer day.
To make sure that the device with the firmware we wrote works correctly, we decided to check it objectively. Another similar device was assembled, and its microcontroller was flashed with a sketch of receiving a signal from the IRremoteESP8266 library. By sending commands from the first device via the mobile application, we ensured that the second device received the same NEC signal that we sent.
Firstly, we can add all the commands of all the IR remotes in the house to the firmware. In this case, the IoT remote control will become a universal device for controlling any household appliances for which remote control is provided.
Use a smartphone app to take the place of all your remote controllers. Simple control of infrared-compatible equipment, like DVD players, TV boxes, fans, and air conditioners (38 kHz infrared frequency). More than 98% of IR devices, including, among others, air conditioners, televisions, set-top boxes, fans, and lights, are compatible with the Lumive IR Smart Hub. The libraries of suitable devices are continuously updated by the cloud.
The Smart universal IR remote controller is compatible with the DIY learning capability. Use the Smart Life app to familiarise yourself with the operation of the remote control of the infrared device if you are having problems identifying the brand of household appliance. So you can use it almost with any gadget in your household.
You can utilize the DIY Learning Function to run additional things since our Smart universal IR remote controller can repeat all 38kHz telecommands from the main controller. You can easily let friends and relatives access your app on their phones by using the share feature.

UEI has been at the forefront of developing entertainment and smart home control technologies for over three decades. UEI was the first to introduce voice control and advanced features such as automated setup and universal control of connected devices through its QuickSet platform. Since 2015, UEI has shipped over 100 million of its voice-enabled remote controls to customers around the world.
The easiest and promising way to register the remote controller is to visit Remote Controller Database website, search the remote controller and download it. For example, as long as you know the remote controller model name, it can be found on the database. I just searched up any LG air-conditioner.
Not every remote controller has been registered to this database. If you can't find yours, you should create it by yourself. Winia makes my air-conditioning system, but it doesn't exist on the database. I've got a local branded TV which doesn't exist on the database either. I had to create them. To create the configuration file, Raspberry PI should be double-checked whether the IR sensor on it captures the remote controller signal or not. First of all, stop the LIRC service.
So far, we have walked through how Raspberry PI turns into a remote controller that switches on and off multiple home appliances. In the next post, I'll build a Power App and Power Automate that talks to an Azure Functions app to access to the remote controller (Raspberry PI) from outside the home network.
Infrared light is often divided into the near infrared, which is closest to the visible spectrum, and far infrared, which is emitted by warm objects. To send a signal to a television, remote controls often use a diode that emits light at around 940 nanometers in wavelength, which falls into the range of near-infrared light.
Some digital cameras have filters to block near-infrared light, but most can detect it. It shows up on the screen as if it were visible light. When you press a button on the remote control, the camera may show a pulsing light emitted by the remote. The pulses are coded to control the television.
Infrared light and visible light interact with materials in different ways. Near-infrared light passes through clear glass and will reflect off metal surfaces, including mirrors. Infrared light passes through most black plastic trash bags, so you should be able to control your television even with the remote covered in plastic.
Traditionally, only simple operations have been supported with the IR remote controller (referred to as remote hereafter). For example, TV can be turned on or off, and TV channels can be changed with a remote. These days, complex and intelligent operations are supported in electronic devices, especially with the introduction of IoTs. For example, smart TVs are equipped with an operating system such as Android [16]. These TVs are connected to the internet and provide various services requiring personal information. To purchase goods and/or watch content, the private and sensitive information such as credit card number, resident ID, or ID/PW should be entered with the IR remote. Smart TV can also serve as a bridge for IoT devices used at home. Thus, users can operate and/or monitor the IoT devices through the TV.
The Wi-Fi Smart Remote allows you to control your home appliances, TVs, air conditioners, and audio/ video systems directly from an app on your phone. Offers voice control capabilities with Amazon Alexa or Google Assistant when linked through the companion app, allowing you to fully control your devices with voice commands.
We buy home appliances every once in a while, and we are adding another Remote controller to our homes, and every device has its own remote control. Thus, the purpose of our work is to control all home devices via the Internet and get rid of using multiple Remote Controls. In this paper, we propose a smart remote controller that can be controlling all home devices and operate them through Internet using the mobile app and it contains a self-learning feature and the ESP8266 is used as a microcontroller. By using our proposed model, people can control the home appliances while they are at work or on the way home on a trip with an easy mobile application and they do not need to learn a lot of remote controllers how it works. Therefore, it can copy all other remote control codes. This is a way to manage many home appliances simply and intuitively. Our experiment results show that the average response time of our model achieved 1.191 seconds.
Infrared remote controllers are everywhere around us. The majority of home appliances are controlled using infrared remote controls. In this article/video, we learn to build a device that can decode (almost) any IR remote control and use the instructions to switch the relays (loads). So we can use this feature in a variety of applications without buying a new IR remote control and expensive hardware, such as turning ON/OFF the lights, opening/closing the curtains, ... I have used an ATTiny85 microcontroller as the heart of the circuit. The device can record up to three IR codes in the EEPROM memory and switch 3 separate devices. Each relay can handle currents up to 10A. The load switching mechanism (momentary ON/OFF, toggling ) can be programmed by the user
I have tested the output of the VS1838 module using the Siglent SDS2102X Plus oscilloscope [16] (figure 6). You can use other models as well, such as SDS1104X-E [17]. The oscilloscope screen says that the signal is clear and noise-free. Each remote control manufacturer might use an existing or its own infrared protocol, and each remote key generates a different code, so the output signal of your remote could be different. I used a SONY HDTV remote control which naturally uses the SONY infrared protocol.
After successful programming of the microcontroller, please disconnect the programmer and restart the board (disconnect and re-connect the power). Then you can store the desired remote control keys (by pressing and holding the SW1). You can change any of the stored keys any time later. The keys are stored in the EEPROM memory, so the power reset does not clear the memory and the stored keys. For more details, please carefully watch the YouTube video.
