Frequently Asked Questions (FAQs)

1. What is an infrared emitter?

An Infrared emitter, or IR emitter, is a source of light energy in the infrared spectrum. This little part is a light emitting diode (LED) that is used in order to transmit infrared signals from a remote control.

2. How do IR extenders work?

An IR (infrared) repeater is a device that transmits the IR signal from a remote control to somewhere it wouldn't otherwise be able to reach. If you store equipment in a closed cabinet, or in another room entirely, an IR repeater kit can reproduce the signal there and allow you to keep components hidden.

3. How do I increase the range of my IR LED?

Re: Extend IR Led Range Reduce 200R to something lower, check the spec of your IR emitter. You can pulse these at much higher currents than always on current. Also make sure the base current is high enough, maybe drop base resistor to 1K or better still.. Swap to using a MOSFET rather than NPN transistor.
