RF Module 433MHZ | Make Receiver and Transmitter from 433MHZ RF module without any microcontroller

[@houseofchez2817]

dude... Way cool. I found you by googling "433mhz rf transmitter and receiver module" and you where on the top returned. good stuff.

[@electronicGURU]

Thanks man 👍

[@houseofchez2817]

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?

[@electronicGURU]

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.

[@thetooginator153]

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

[@electronicGURU]

Yes you can and it might work but i am not 100% certain.

[@MarkAnthonyCTutor]

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

[@ashuvidhani3283]

Can I use a 9 volt battery to the transmitter circuit ??

[@electronicGURU]

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.

[@shashanktg08]

Can I connect 5v realy instead of led over there in the circuit

[@electronicGURU]

yes you can

[@indianarduinoprojects8753]

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.

Can you tell me what the current consumption of receiver module when ideal ON but not receiving anything?

[@electronicGURU]

no idea , you should check datasheet

[@arvand26]

And why only 4 chanel? That ic have more pin? Can you explain?

[@electronicGURU]

Actually only 4 are there. Which pins are you referring to by the way.

[@vidhaniprakash5763]

There are two data pins in receiver circuit which one to connect in pin 10

[@electronicGURU]

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.

[@Kaonashi-8]

Can this "no mcu" be applied to sensor networks? for example temperature sensors and pulse sensors?

[@electronicGURU]

I mean you can but if you are already using sensor network which might have internet connectivity so why use RF ??

[@Kaonashi-8]

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

[@spr1813244]

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.

[@badgthom]

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!!

[@alcyonvega5101]

Great video! Please, how did you calculate resistor values used (1M & 68K)?

[@electronicGURU]

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.

[@sauraviotdeveloper7094]

What is the range

[@utkuserin9750]

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?

[@harshajazzdrummer]

What about range of the red module 433 mhz

[@electronicGURU]

30-50m

[@mnk8630]

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?

[@electronicGURU]

well depends on your encoding sir.

[@mnk8630]

@@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?

[@electronicGURU]

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

[@shubhambiswas8627]

Can use 12 volts to receiver?

[@JesusRemix]

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.

[@fabianarevalo2198]

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?

[@bhogalandson]

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?

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.

[@electronicGURU]

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.

[@Willy_Tepes]

​@@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.

[@electronicGURU]

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

[@Willy_Tepes]

​@@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.

[@electronicGURU]

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.
