Hello, everyone.
This is KinCony IoT lessons.
This is lesson four.
I will show you the smart
solution of infrared device.
The ir means Infrared device.
Let's begin
for ir what device is IR?
you commonly used the
TV DVD or maybe your fan,
or your air condition.
Yeah, yeah yeah.
Maybe you have a TV
and DVD and have a fan
and the air condition,
the IR device, maybe you
have this three type,
and you can will have many other IR devices,
just they are all have a remoter.
This is a remoter.
Because the TV
we can use the remoter to control,
change the channel or change the volume
or the DVD we can skip the video.
previous video and the fan,
we can change the speed, a low
speed, high speed, middle speed,
or the air condition, we can change
the temperature and the work mode.
All this device will have a remoter.
We need that this device
traditional device becomes smart.
We can add a wireless gateway
This is KC868-G
this can send the IR signal.
The principle is we can
learn the signal.
The principle is we can learn the signal,
the remoter to the gateway
like the TV power on DVD chose next video.
So we can learn the signal.
then we can send the signal.
The learning code send to these devices.
so we can control device instead of
manual control by this remoter and
this we can use mobile phone,
mobile phone to control the gateway.
Maybe you can use the PC software
or you can use other platform software
like home assistant or like Node-Red
or other software just,
send command to the gateway and send
the signal to the device have learned.
So this is easy way to control all
these devices that have the remoter.
And three, we can see the
signal type of the IR device,
maybe you have press a button
press a button like
a button when you press.
There will be compose with many signal.
Maybe if you have a turn on the TV,
or power ON,
or you can press the DVD
like the pause
We'll send a signal.
This signal is the code of the button.
And the second,
the different
is the air condition.
The air conditioning will have many signals.
Many signals.
The length was more long than this
simple function,
this air condition like this.
If you want the air condition
work at 20℃ centigrade,
there will be also include the speed of
the fan and also have the work mode,
uh like,
maybe a cool or maybe hot.
This whole signal is for air condition.
This is for temperature.
This is for speed.
This is the work mode.
All this signal,
when you press about please sleep.
This three Information have been sent,
but this button,
just "power on" or "pause" or other function,
just only one function.
So the length is short.
This length.
It's long.
When we read and learn the air condition
make sure know the difference
if set 20℃ temperature,
there will be two work mode.
one is "COOL" work mode
other is the "HOT"
When you learning the temperature,
you need to make sure the
temperature is in cool work mode.
When you're learning
the temperature is in hot,
work more you are learning.
So we'll send different signal.
Another example,
when you control the power power on
and power off of the air condition.
When you learning the power on,
it will have these three Information,
like, the temperature,
and the speed,
maybe the speed is low.
The work mode is cool.
So all Information will send it.
If you have used the power off,
but learning,
this is one command.
This is only one command for power off
not include these Information.
So when you power on so you need to
make sure you remoter's current,
the work mode,
and this speed,
fan speed, and the temperature.
You need to make sure.
So when the "power on" is send these
Information at one signal.
This is the principle,
just learning the signal
and send to the device.
This is a signal compose.
And the fourth,
we can see how to place?
Place the gateway to the right position.
If you have a room,
this is a TV
maybe this is air condition.
Besides that TV
this is TV, this is air condition.
So we can put the gateway
in front of this device,
because they are transmitors,
IR transmitors inside of the gateway.
So it have many different
directions to send the signal.
You can place the device,
in this position,
or may be in this position,
or is no problem.
just the gateway can send
the signal directly.
If you have another room,
this is another room.
This is wall.
And this position have an air condition.
If you want, let this gateway
to send them Information,
send the signal to this air condition.
This is wrong.
The signal can't go through the wall and,
send to the air condition.
So in different room, you need to
put another new gateway.
This is a new gateway.
And
This gateway can send signal to the device,
maybe in this place, this place.
So it can send two different directions.
And this gateway all
connect with the internet.
So you can use a mobile phone.
This is a mobile phone.
The gateway is inside.
This gateway also is inside.
You need just one application to
control different.
Gateway
control different device,
electronic device,
all in one application.
And also, maybe you have the DVD or STB
Maybe have a fan
just use one.
Gateway is enough,
not need to put many, if there is a wall
at this position
This is a device.
This signal.
can't send to this device.
You need to put a new gateway,
a new gateway
for this device.
So this is the principle of the wireless IR.
Device, the wireless solution
use by a mobile phone.
This is how to.
Place gateway in a room.
How to choose the position.
Now you can understand the IR signal and
the principle how to place the gateway.
You can, according to your room's
size and the device position,
you can change how many gateway to place.
And where to place the gateway.
Okay, thanks for watching.
