How to use 433 and 315MHz pair | RF | Wireless | Remote Control Systems | Home Automation

This is a series about Wireless or remote control systems, In this first video of this series, we will see how to use these cheap Rf433 and 315 MHz transmitter and receiver pairs. We can also do Home automation using these Modules as we will see later in the Series.

Loved this.. You are really underrated bro. More support to you ❤️🙏

[@jitulex]

Thank you 🙌

[@planker]

Well done. I will be Subscribing . I added a 3T coil to the TX only and had no effect. I did not modify the RX. A pack of five all worked. 3 RXs needed slight adj. Perhaps a distance test using or not using coils. Good call on the Capacitors on the TX side, lots and lots of noise form switches and stuff.

[@jorgesuarez3368]

Very good and interesting your post!! Congratulations!! Just one question: as soon as I connect the source (even without connecting the RF emitter), the LED turns on... It turns off when I press the switch. It's right? How do I make it off by default and turn on when the switch is activated? Thanks for your answer!!

Thankyou sir.

[@btzee]

Do you have any information of Rolling codes in RF system, like we have in Car FOB keys, keeloq? How should one go about implementing these in one's system, if one wants to make them more secure, than the fixed/learning type systems which can be amenable to replay attacks...

Qual foi o resistor q vc colocou no receptor

[@euphoriachemistryclasses1383]

I made RC car using FS1000a 433Mhz TX and Rx module. I use 1M resistor in Transmitter circuit and 33k ohm resistor in reciever circuit but the circuit is not working. Can you help me ? I am using 5V.

Is there a reason for difrences between these boards and a "433Mhz"? I got a board without the added components that a 433Mhz has, though it is advertizesd as 433Mhz. Is there any parts I need besides a coil to use my board? Why dose it have missing parts compared to the other board type? Anway, great video!

[@jitulex]

Apparently these modules are not very reliable, the connection between them is very unstable hence i dont use them much in my projects, but if you wish to you can try to use it as a 315mhz module by not connecting more components to the board, the reason why this board has missing components is because these modules were initially designed for 433mhz only but i guess to fill the market, people also came out with the 315mhz option but just modifying the oscillator section of the modules and changing its frequency

[@zacharyhisaoka9194]

@@jitulex yea I just switched to a better module. Nrf24L01 seems to work but I haven’t tested it yet

[@jitulex]

It works fine just requires 2 seperate microcontrollers on each end, transmitter as well as receiver hence increasing the cost dramatically compared to the 433mhz as well as these modules work on spi and coding for them to work properly increases complexity.

[@amyneko]

Hello! for me it only works if i operate both modules from the same power supply. the second i use them from a different one it dosent work. I have 2 five volt power supplies I made them both and I checked and they work.

[@aydeesam1768]

Hi..just came ro say thanks for the video, but i have a request if you can fulfill and that is how can we send water level sensor data to receiver using these rd modules? For example i want to send water level measurement from 1 to 10, water temperature and possibly live camera video from overhead tank to receiver available at ground

[@jitulex]

Thanks for your comment, i already have a video in making about sending data with these rf modules, and that data can be anything, like water level information or anything you want, so subscribe and dont forget to press the notification bell so you wont miss that video!

[@aydeesam1768]

[@mohamedmaher4696]

Thanks for the explanation but I still have a problem The led in the receiver always on and it has some noise When I press the button , the led decreases its intensity a little bit only

[@jitulex]

that is due to the bias on the data pin, if you connect an digital encoder and decoder ic to the setup, it will be able to detect this high and low as digital signals, try that out, i have a seperate video about it so do give it a try, if the problem still persists, do leave a comment

[@Trofew]

Молодец. Респект автору. Единственный указал в чем разница и как с этим бороться.

[@jitulex]

Thank you!

[@DavidH-Calgary]

What is the value of the resistor you have placed between data and negative on your receiver circuit?

[@jitulex]

There is no resistor connected between data and ground in any of the circuit

[@deepakrautela9342]

Can we make passive keyless entry system for bike using 2 pair of txr-rxr ? Means one txr is always on (bike side) when always on rxr (of key) comes in close proximity, it will activate txr(of key). In turn (rxr of bike) will get activated and bike ignition will be ready. Please guide me. How much current Will always on rxr (of key) consume? Will it sustain on coin cell for 1-2 months?

[@artidwivedi67]

The LED of my receiver glows , even if I don't press the transmitter button , please tell what could be the problem

[@artidwivedi67]

Fast

[@jitulex]

The connection between the tx and rx modules possibly would be bad or non existent.

[@jitulex]

Try replacing the tx and rx modules

[@jitulex]

Or double check your connections

[@artidwivedi67]

K thanks

[@TejinderSingh-ul5wi]

Hii, can we use LDR light Sensor instead of Button Switch?

[@jitulex]

Yes you can but you have to make sure that the sensor is working in the active low state, which means when the sensor detects something then it will give an 0 at the output

[@aloneforest6513]

is that 433mhz modules only can do one channel? so ı can't control 4 different things with it, only one? What if we use arduino, can they function as multi channel then?

[@ommakane453]

Does the kedsum one way remote operates at 315mhz or 433mhz? Can anyone tell me?

[@Tlgamingz]

Can I use motor instead of led bulb please reply fast there is a project

[@jitulex]

Yes you can connect the output to an motor driver ic like the l293d and connect the motor to the ic

[@Tlgamingz]

Is it work without l293d ic

[@jitulex]

Yes you can use the output to turn on a transistor with a resistor on its base

I not understand

Bhai mera rf module mai ek problem aari hai ke Yea bina switch on kre he jalta rehta hai aur switch on krne pr Sirf ek baat jalta hai fir band ho jata hai jaise ke switch ya transmitter ka koi asar he na ho Sirf receiver khud Kaam kr rha ho

[@jitulex]

Are you talking about the HT12E and HT12D system?, I can presume that because you mentioned switch, so I have an separate video on that and how it works, check that out, check that all your connections are right according to what I showed in the video, then if it still doesn't work, leave a comment on that video, the link is: kzbin.info/www/bejne/oJmknqewp8iIqMk

Can you design the same circuit without using RF transmitter and receiver module's

[@jitulex]

What do you mean? Can you be a little elaborative? Which circuit do you need to be designed?

[@kamleshchavan7451]

@@jitulexSir very first thing thanks for the reply , a circuit with no transmitter and receiver module used separately , for example if you see in simple Remote Control circuit used in RC toys , to control the motors ( servo motor , dc motor etc ) .There's no transmitter and receiver module's used in the RC toys. , no transmitter module in the transmitter or no receiver module in the receiver side . So any circuit Explaining how the signal is transmitted from transmitter to receiver to control the motors in toy. There's no transmitter and receiver module's used in the RC toys.

[@kamleshchavan7451]

Sir I don't want to disturb you , maybe I am able to explain you what I want , but still trying my best , can you make the same circuit of the transmitter and receiver module's you are using ,on the bread board , do you have the circuit diagram of module's , just wanted to know working of the circuit , of the transmitter and receiver module's , how the signal is transmitted from transmitter to receiver to control the motors or leds

[@nagalokesh7337]

I don't know much about but the transmission and reception in rc toys use same principle. The input signal is multiplexed into higher frequencies using a set of transistors and crystal oscillators and then it is fed to a antenna and is received at receiver and Demultiplexed. Making a rf circuit with higher range is not preferable as it needs license. Hence you can use the modules with license. You can even google how rf circuit works for precise and better information.
