An IR Blaster (Infrared Blaster) is a device that emits infrared signals to control other electronic devices, similar to how a traditional remote control works. It acts as a universal remote, allowing you to operate TVs, air conditioners, set-top boxes, sound systems, and other IR-compatible gadgets.
How Does an IR Blaster Work?
- Sends IR Signals – It transmits infrared light pulses that match the codes used by your devices.
- Works with Smartphones/Apps – Many modern smartphones (especially older models) had built-in IR blasters, allowing them to function as universal remotes via apps like Peel Smart Remote, Sure Universal Remote, or Anymote.
- Smart Home Integration – Some smart home hubs (like BroadLink RM4) include IR blasters to automate control of non-smart devices.
Common Uses of an IR Blaster
- Control multiple devices (TV, AC, DVD player) with one smartphone.
- Automate home appliances via voice assistants (Google Home, Alexa).
- Replace lost or broken remotes.
- Create custom remote control setups (e.g., turning on TV + sound system with one command).
Devices with Built-in IR Blasters (Past & Present)
- Smartphones: Samsung Galaxy S6, LG G5, Xiaomi Redmi Note series (older models), Huawei Honor 6X.
- Dedicated IR Blasters: BroadLink RM4 Pro, Logitech Harmony Hub, FLIRC USB.
Alternatives If Your Phone Doesn’t Have an IR Blaster
- Wi-Fi/Bluetooth Smart Remotes (e.g., BroadLink, Logitech Harmony).
- USB IR Adapters (for PCs/laptops).
- Smart IR-enabled hubs (for home automation).
