dude... Way cool. I found you by googling "433mhz rf transmitter and receiver module" and you where on the top returned. good stuff.
Thanks man 👍
I'm a retired EE from the old school... of the 70's-80's business and engineering computer era... bought a Tx and Rx set long ago..it's been in my "parts-is-parts' collection over 6 years at least ... never had a solution that required it until now...
I'm doing a pushbutton (momentary contact) switch (with an RC denounce) that Tx sends to the Rx to toggle a J/K that drives a single OTS Arduino marketed relay board...
your thoughts on this project?
Could you please explain the exact application you are looking for? And what components you have which you want to use? That will be helpful for me to understand your approach and i will provide you my thoughts on that.
I haven’t tried this yet, but it’s EXACTLY what I want to do. Great video! Thanks!
Thankyou so much bro. I was stuck at this part(which happens to be the underlying part of my project) for days. Finally you got me out of this !! Lots of love.
Can i use 3 AA size battery each of 1.5volt in the transmitter circuit so will it work and i want to use motor driver with this circuit so the +5v pin of l293d motor driver can i connect it to 3 AA size battery.. please reply
Yes you can and it might work but i am not 100% certain.
What power supply should i provide as i don't have a 5 volt
Battery can i use two lithium
18650 ion cells in the receiver circuit and add a 5 volt regulator ic
Each of 3.7volt
Yes that would work but make sure its 5v.
Hello can i connect one transmitter into 2 or more receivers?? Pls cause i have an incoming project with regards to that as of now i can't see any links about that. Thanks
Wonderful video! How would I connect multiple transmitters to a single receiver and have the receiver illuminate a separate led light when each individual transmitter is triggered? I'd prefer it if I didn't have to use arduino as there is very limited electricity and no wifi. Thanks!!
Hello Sir I have a question can I send on signal instead of off signal to the receiver? by the way nice video Sir keep up
If i connect two resistors in series connection each of 100k so will it act as a 200k resistor please tell .
I know that this query is not related to your current video then also please tell me
Yeah obviously it will work since that is the basic resistance rule.
@@electronicGURU thanks bro for your reply.😉😉
Your welcome
@@electronicGURU i also have one more doubt and posted it in comment section can you please answer it
What doubt please ask it here. I couldn't find it.
If i want a DC motor to run forward when i press one button and backward when i press another button how i can do this task wireless using rf circuit please reply
Well connect two pins of tx to the motor driver and if you press one button on tx it will run motor forward and other will run it backwards.
Hello, I have multiple receiver modules but the circuit only worked with one. I tested each module individually with a simpler test without encoding and it seems to work. But when encoding it only one receiver works. Why is this?
Thanks for your great Video. can I send continuous audio with this device?
I have 2 quesions.
Does the resistor on the rf reciever essentially needed? And these two Rosc resistor values needs to be exacly same values with video? What is the its importance?
Thanks for the video, would I be able to use the receiver output (like the LEDs) with an MCU to read if a pin is high or low? Just to let everyone know from my testing it seems to have a pretty good range of at least 5ft or roughly 1.5m without the antenna, provided you are able to supply the recommend minimums to each circuit.
what is the range of small green rf module
20-200m
This is awesome. I wanted to use this approach to make a thing finder in the house for things like keys, tv remotes, etc. My idea would be to add a battery powered version of this to each device I want to be able to locate. My question is does your approach only allow for 4 receiving devices?
TV Remotes use much simpler approach. they use IR transmitter and receivers with delays. much simple and very cheap to implement
If I would be using two pairs of transmitters and receivers at small distance, is there a possibility of signal interference and result might suffer in both the receiver end?
well depends on your encoding sir.
@@electronicGURU okay… thank you… for the information… but i have one more doubt that these pair of transmitter and receiver dont have any unique identification so how they communicate if there are more than one transmitter and receiver?
well on encoder and decoder have 8 pins to set the encoding of rx tx so if you have making few pins of encoder high then the same thing needa to done for decoder too ,
so if any tx has some status (any) of those 8 pins and few rx has same thing too then they all can receive the data sent by tx
Thank you so much for the easy explanation
your welcome
Can you tell me what the current consumption of receiver module when ideal ON but not receiving anything?
no idea , you should check datasheet
Great video! Please, how did you calculate resistor values used (1M & 68K)?
For HT12D & HT12E ICs if your refer datasheet for these decoder & encoder IC you will be able to see that 51k & 1.1M is prescribed for these. So i was having values of 68k & 1M so i went with those. Because they are nearly similar values.
I'd like to save power when transmitting from battery power. What would I add so that it only reads and sends the temperate say every 10 minutes.
Use a latch.
how about a even simpler Tx to Rx set up, where : when Tx is powered up Rx has 1 pin going to +5v so I could connect a cell phone vibrator ? Could I use the same parts you selected and do that ? the range I need would be around 125 to 150meters any suggestion ? TY very much for your vids Cheers
Can I use a 9 volt battery to the transmitter circuit ??
According to datasheet transmitter can be run by 3-10V but not sure about HT12D i think HT12 D runs on 5v only well the best idea would be to use a cheap 7805 if you wanna use a 9V battery.
what is the output V to the leds ? would that voltage be enough to make a cell phone vibrator work ? how can this be boosted to get 150M range if that 's possible ? Thanks for the knowledge Cheers !
Bla D Good! Thank you. !! Nice and simple. WiFi eat your heart out! This Lots less complicated. Nice IC Chips
Thanks man 👍
Bro i want to tranmit sound through rf module over short range of 30 cm so is sound quality will be affected or not and if it will then whats the solution
I think it will be effected and i am not sure if they will able to do it properly and i will try to do this might be a good topic for next video. so try googling people have transmitted Audio over NRF with Arduino that might be usable.
Should i use amplifier to reduce noise
Well you can try. It might work.
Please check a video from greatscott UA-cam channel, he makes a walkie talkie using these modules.Here is the link ua-cam.com/video/PKowvbnIxso/v-deo.html
Ya i follow him 😅😅
The same steps if we use cheap ???
Can this "no mcu" be applied to sensor networks? for example temperature sensors and pulse sensors?
I mean you can but if you are already using sensor network which might have internet connectivity so why use RF ??
I am using Proteus to simulate it, so I have created not a wireless internet connectivity, but a network using RF module. @ electronic GURU however, I want to reduce number of arduinos from 4 to just 1
And why only 4 chanel? That ic have more pin? Can you explain?
Actually only 4 are there. Which pins are you referring to by the way.
Can i use 1megaohm 1 watt resistor
Becsuse i dont have 1/4 watt resistor
Yeah that could work.
i will do transmission long distance. so can i need connect for the antenna?
Yes you can
your sharing is clear and easy understanding. Thanks for your dharing.
Sir, can i use without switch? When tx n rx close together n they are immediately connect
Yes you can. It totally depends on your circuit.
@@electronicGURU can you show the wiring for my question? Or just connect pin 7/8 to ground?
Is it possible to have single transmisster and many receiver?
Yes, I’m pretty sure.
Can I connect 5v realy instead of led over there in the circuit
yes you can
Is there a Rf433 encoder inside????
Good project sir
It is very good option for for cost efficient project.
👌👌👌👌👌👌
Great video, Good Explanations ,Good Job Man Keep It Up 💪
I need to transmit signal to the distance of 256meters?
make a proper antenna
Many thanks for making great video... I always love your hard work .. we learn lots from you my big request plz always make this type video
There are two data pins in receiver circuit which one to connect in pin 10
Well try with of them depends on module , mostly both works, but for me the closer to GND pin was working perfectly. Some people even use both together and some use one. So it depends on your module etc.
Good video and good learning.
Thanks man 👍
And what'sthe story with the bug running across and under the boards at 4:36???? :-) by the way, if you solder 17.3 cm wires on both TX and RX and coil them you can increase the range quite a bit. Nice little weekend project.
Well done sir
I didn't find any single youtuber who can explain the circuit diagram of the 433 mhz transmitters and receiver module
how it works, how the data or signal moves from transmitters to the receiver
Can you please tell me the colour code of 1 megaohm resistor and 68 k resistor
1M-ohm -> Brown, Black, Green, Gold
68k-ohm-> blue, grey, orange, gold.
What is the range of this transmitter?
It's very useful , thank you for teaching. Already subscribed.
Amazing tutorial bro
But your English is like Great Scott.
Thanks man 😄😌
Can anyone help me with my project. I'm following the steps in the video but came up with a problem my led keeps on blinking while data pin of the transmitter was on the ground
Can you share me your schmatics ? And what are you trying to do and have to tried to use any other pin or any other module except the one you are using.
I'm following your schematic sir. I don't use any module coz i only have one.
Can use 12 volts to receiver?
Can we use for drone
I mean if you want you can , but it is Highly not recommended because for drones if signals lags by a few mili seconds even it would crash so. Go for NRF24L01 or something.
What is the current of the transmitter when idle?
Honestly i haven't measured it , please check its datasheet.
nice review... please make a more videos
Yeah sure , check my recent videos. You will find some more videos related to these.
What about range of the red module 433 mhz
30-50m
best video ever
Can i make this for helicopter also
Can I transfer stereo audio?
It may be possible but i am not totally sure but theoretically we can but it will be needing alot of things. With the setup i used in the video its not possible to transmit audio i think.
Sir can u make a vedio? (for Wireless water level controller with these transmitter and receiver) plz help me.
thank you!!! 👌🙏👍
Can you tell me what will happen if i dont connect an decoder and encoder
@@electronicGURU can u suggest a simplest icu
for connection
@@electronicGURU yes...i want to just make a led work with a switch
Uauu great project! Can u help to make a an project? A long rang alcance ring door bell?
Great! Thanks best content!
can this IC make 8 channel bro???
Actually this IC can't.
@@electronicGURU i bought rf433, but without ic, i can't make 1 channel remote. why?
@@electronicGURU is this video correct? ua-cam.com/video/98tYLEnevfA/v-deo.html
@@electronicGURU I tried to make it like in the video. 1 channel rf433. but always failed
Thank you sir
Useful video
Sir, can i have a copy of schematic diagram? Just need for project thanks.
Can i use it to create a remote control?
You help a lot. Thank you!
electronic GURU sir how can i contact you in private
just want to ask something
Great! Thanks for the content!
Your welcome brother 👍
What is the range
How much do all this costed you.
100 rupees hardly
superb video.
I just want a1 led to work with a switch can u trll me the circuit
I do it exactly like you do but it is not working
@@electronicGURU same for me... it didn't working
really thanks u
hi @@UCJmFy7YSogeWXwmXOfRJ6JQ , i want to make a remote switch to control light. this seems a good idea.
on the transmitter side i have no choice but to use a battery to power transmitter. but on receiver side (which would operate the relay) I have 2 options: either to power receiver using, say a 9 v battery (which drains like crazy) or use the line 230v to 5 vdc buck converter. my question (doubt) is if this buck converter will always consume power? in that case it would be wise to use (may be a rechargeable) battery.
Well i would suggest to get those HFLINK like ac to dc small modules they will cost something 100 rupees and they can convert 220v ac to 5v dc do they will ideal in your case.
Nice sir can I send audio by
rf433 module

You could have given more explanation about pcb connection
Can we make a drone using it
@@electronicGURU can they transmit audio?
Hello DesiScott!!!!!!
@@electronicGURU ur content is that quality ...
Ill give u an idea for next vid : stm32 based vfd .
You said "without an MCU", yet I see an MCU :/
Try this with just push button and LED. You push button on one end, LED lights up at other.
The one you think is an MCU is just a encoder and decoder IC and if you think its an Mcu then i'll tell you that you can build an decoder & encode IC just from transistors, complex but not programmable as Mcu and yes we can do that as you recommended but it won't have any proper application.
@@electronicGURU I just need a simple detector that transmits when triggered. No more complicated than a alarm system sensor (IR/magnet switch/pressure pad). Such a simple circuit can also be used for communication in Morse code. What I need only requires an on/off signal, no coded information.
We have bears in our forests and I'd like to set up a early warning system around my camp site with trip wire. If I could make the receiver fit with a wrist band on my arm it would be nice.
Oh you can use the same setup i used with a laser and ir receiver and whenever laser gets tripped it will have transistors which will break the circuit and the receiver gets triggered. Something like that
@@electronicGURU Oh, it is really that simple? I'm relatively new to electronics, but that sounds like something I could make easily. If I put a 555 timer on each transmitter and tuned them differently I could know which detector that was tripped by the intervals of transmission. I just need a buzzer on the receiver.
It is a good idea for a video as no one else seems to have uploaded anything like that.
Thanks for sharing i would suggest to add a microcontroller instead, it won't cost much use any cheap one and program whatever functionality you like it will save you alot of trouble of using 555 and identifying intervals because sometimes its hard to get exact intervals on these 555.
Cool
