In today’s world of smart devices and advanced technology, the ability to control multiple devices with a single remote has become a coveted feature. The Infrared (IR) blaster is a key component that enables this functionality, allowing users to manage their devices with ease. But does the A21, a popular Android TV box, have an IR blaster? In this article, we’ll delve into the world of IR technology, explore the benefits of an IR blaster, and provide a definitive answer to this question.
What Is An IR Blaster?
Before we dive into the specifics of the A21, let’s take a step back and understand what an IR blaster is. An IR blaster is a device that sends infrared signals to other devices, allowing them to be controlled remotely. It’s essentially a transmitter that converts digital signals into infrared signals, which are then received by devices equipped with IR receivers.
IR blasters are commonly found in remotes, smartphones, and other devices that need to control external appliances, such as TVs, DVD players, and air conditioners. They’re an essential component in the world of home automation, making it possible to manage multiple devices with a single remote.
How Does An IR Blaster Work?
To understand how an IR blaster works, let’s break down the process into simple steps:
- A device, such as a smartphone or remote, sends a digital signal to the IR blaster.
- The IR blaster converts the digital signal into an infrared signal.
- The infrared signal is transmitted to the target device, such as a TV or DVD player.
- The target device receives the infrared signal and performs the desired action, such as turning on or off.
This process happens rapidly, often in a matter of milliseconds, making it seem instantaneous to the user.
The Benefits Of An IR Blaster
So, why is an IR blaster such a valuable feature? Here are some benefits that make it an essential component in many devices:
- Convenience: With an IR blaster, you can control multiple devices with a single remote, eliminating the need for multiple remotes cluttering your living room.
- Easy Automation: IR blasters enable home automation, making it possible to control devices remotely and create custom automation scenarios.
- Universal Control: IR blasters can control devices from different manufacturers, making them a universal solution for remote control needs.
IR Blaster Vs. IR Receiver
It’s essential to understand the difference between an IR blaster and an IR receiver. While both components are related to infrared technology, they serve distinct purposes:
- IR Receiver: An IR receiver is a device that detects infrared signals and converts them into digital signals, which are then processed by the device. IR receivers are typically found in devices that need to be controlled remotely, such as TVs and DVD players.
- IR Blaster: An IR blaster, as mentioned earlier, is a device that sends infrared signals to other devices, allowing them to be controlled remotely.
Does The A21 Have An IR Blaster?
Now, let’s get to the main question: Does the A21 Android TV box have an IR blaster? The answer is no, the A21 does not have a built-in IR blaster.
However, this doesn’t mean you can’t use the A21 to control other devices. The A21 has a built-in IR receiver, which allows it to receive infrared signals from other devices. This means you can use the A21 to control other devices, but it cannot be used as a transmitter to send infrared signals.
Workarounds For The A21
If you need an IR blaster for your A21, there are a few workarounds you can consider:
- External IR Blaster: You can purchase an external IR blaster that connects to the A21 via USB or wirelessly. This will enable you to control other devices using the A21.
- Third-Party Apps: Some third-party apps, such as AnyMote or IR Universal Remote, can emulate an IR blaster on the A21. These apps use the device’s screen to transmit infrared signals, allowing you to control other devices.
Conclusion
In conclusion, while the A21 Android TV box does not have a built-in IR blaster, it’s not the end of the world. With workarounds such as external IR blasters or third-party apps, you can still use the A21 to control other devices. Understanding the benefits and functionality of an IR blaster can help you make the most of your devices and create a seamless home automation experience.
| Device | IR Blaster | IR Receiver |
|---|---|---|
| A21 Android TV Box | No | Yes |
| Smartphone | Yes | No |
| TV | No | Yes |

What Is An IR Blaster?
An IR blaster is a feature in modern smartphones and other devices that allows them to control other electronic devices that use infrared remote control, such as TVs, air conditioners, and DVD players. This feature works by sending infrared signals to the device, mimicking the signals sent by the remote control. This means you can use your device to control multiple devices, all from one interface.
IR blasters are typically found in high-end smartphones and are often used for convenience, allowing users to control multiple devices from one place. They can also be used to simplify the remote control process, reducing clutter and making it easier to find the right remote.
Does The A21 Have An IR Blaster?
Unfortunately, the A21 does not have an IR blaster. This means that it is not capable of controlling devices that use infrared remote control, such as TVs or air conditioners. While this may be a drawback for some users, it’s worth noting that the A21 is still a powerful device with many other features.
If you need to control devices with an IR remote, you may need to consider a different device that does have an IR blaster. Alternatively, you could use a separate IR blaster device that can be connected to your A21 or other devices.
What Are The Benefits Of Having An IR Blaster?
Having an IR blaster can be extremely convenient, especially for those who have a lot of devices they need to control. With an IR blaster, you can control all of your devices from one place, eliminating the need to search for multiple remotes. This can be especially useful for people who have a lot of devices connected to their TV, such as DVD players, game consoles, and streaming devices.
In addition to convenience, IR blasters can also simplify the remote control process, making it easier to use your devices. They can also be used to automate certain tasks, such as turning on multiple devices at once.
Can I Use A Separate IR Blaster Device With The A21?
Yes, if you need to control devices with an IR remote, you can use a separate IR blaster device that can be connected to your A21 or other devices. These devices are typically small and can be plugged into the headphone jack or USB port of your device. They then send the IR signals to the device you want to control.
Separate IR blaster devices can be a convenient option for those who need to control devices with an IR remote, but don’t want to upgrade to a new device with an IR blaster. They are often inexpensive and easy to use, making them a great option for those who need additional remote control capabilities.
What Devices Can I Control With An IR Blaster?
IR blasters can be used to control a wide range of devices that use infrared remote control. This can include TVs, DVD players, Blu-ray players, streaming devices, air conditioners, heaters, and many others. As long as the device uses infrared signals to receive commands, it can likely be controlled with an IR blaster.
IR blasters are also often customizable, allowing you to program them to control specific devices or functions. This means you can use your IR blaster to control devices that may not have been originally intended to work with the feature.
Are IR Blasters Still Useful In The Age Of Smart Devices?
While many devices are moving towards wireless connectivity and voice control, IR blasters can still be useful in many situations. For example, not all devices are yet compatible with wireless connectivity or voice control, so an IR blaster can be used to control these devices.
Additionally, IR blasters can be used in situations where wireless connectivity or voice control may not be possible, such as in areas with poor wireless reception. They can also be used to control devices that are not connected to the internet, such as older TVs or DVD players.
Will The A21 Ever Get An IR Blaster?
It’s unlikely that the A21 will get an IR blaster, as it is not a feature that was included in the device when it was released. While it’s possible that future software updates could add IR blaster functionality, this is not a common practice and is unlikely to happen.
If you need an IR blaster, it’s best to consider a different device that already has this feature. Alternatively, you can use a separate IR blaster device that can be connected to your A21 or other devices.
