What is the difference between IR and RF remote controls?
IR stands for Infared and means the remote must be pointed directly at the receiver. RF stands for Radio Frequency and means the remote is multi-directional. Radio Frequency (RF) operation provides up to 100′ range though walls, floors and doors, indoors or outdoors.
Does IR remote need line of sight?
Infrared uses pulses of infrared light to transmit data from one device to another. The Infrared technology has a signal range of about 10 yards and requires line-of-sight. Radio frequency (RF) is a data transmission technology which is based on electromagnetic radio waves.
Are there different protocols for IR remote control?
As I was perusing the SB-Projects site on the different IR protocol formats, I decided to make a summary but later found out that it was a pretty standard thing, as documented by a Vishay document “Data Formats for IR Remote Control” (pdf).
Can a microcontroller decode an IR signal?
Hence, It can be a little bit tricky to decode the signal from a microcontroller. In this instructable, I’ll Explain how we can easily decode IR protocols of any AC remote.
How can I check if my Remote Control sends an IR signal?
Check if the IR Remote Control Sends Infrared Signals. Turn on your camera or the camera on your cellphone. Point the end of the remote control with the IR emitter to the camera or camcorder lens or cellphone screen. Press and hold one of the buttons on the remote control. Look at the viewfinder or LCD screen.
Do you need to know the IR protocol?
If you have no idea what protocol this is, you could browse through the different IR protocols, looking for a match. However, if your aim is to simply to replay the IR signal, then you’re done – just choose suitable values to simplify your code. The IR protocol is unlikely to use many different durations, due to previously stated reasons.
