What Is an IR Blaster?

An IR blaster, also known as an infrared blaster, is a device that allows you to control other electronic devices such as TVs, cable boxes, and home theater systems using a remote control app on your smartphone or tablet.

IR blasters typically work by emitting infrared signals that are similar to those sent out by your remote control. These signals are then received by the device you want to control, allowing you to perform functions like changing channels, adjusting volume, and turning the device on and off.

Many smartphones and tablets are equipped with IR blasters built into them, which allows them to act as remote controls for a wide range of electronic devices. This can be especially useful if you have multiple devices with separate remote controls and you want to consolidate all of the controls into a single device.

However, not all smartphones and tablets have IR blasters, so you should check your device’s specifications to see if it has this feature before attempting to use a remote control app.
