Project Description:
********************
As I said earlier, things get a little complicated when it comes to multiple sensors connected with multiple transmitters. The sensor values from the multiple transmitters based on the NRF24L01 Transceiver modules are sent to the single receiver. Now, at the receiver side, you should know exactly which value belongs to which sensor and from which transmitter the sensor value is received.
These are the transmitter and receiver circuits that I used in the Long-range industrial temperature monitoring system. Now to explain the idea of how to use multiple NRF24L01 transmitters with a single receiver I made another Transmitter circuit. For demonstration purposes, I will use only two transmitters, but you can increase the number of transmitters which I will later explain in this video. So, as you can see both the transmitters are exactly the same. I have connected two potentiometers which I will use as the sensors. You can also increase the number of sensors as I have already used an array in the programming which can be used to store values of the multiple sensors.

Thanks Batticha Shumami.
This is an excellent, well made tutorial! I have been searching for what this presentation covers for days! Thanks for making this!
Looks good! Als a project I made almost the same but with the nrf24mesh module. That has the advantage of trying to find a route to the endpoint by itself if a relay-point fails.
Great video
Very nice video
Thanks for the great content. One comment - for those sensors at the lowest level in the network that will be wired to the MCUs, you just need a transmitter instead of a transceiver since you are only reading from those sensors.
Tank you very good
Very very great useful video ♥♥♥
thanks Shaker.
Este canal é fantástico! Tem me ajudado muito no meu desenvolvimento.
Nice project
Finally found a very good tutorial for multiple nrf network data communication. Thank you!
very soon will upload the other two versions
On the first part, I encountered an error on the receiver side. I just deleted "done =" from radio.read(data, sizeof(data) ); Now it works! Also noticed the last recorded values remained after turning Off the transmitters. Might need to modify if statements to default to zero.
@@ElectroniClinic I have a small problem. I need to use components that are compatible with Arduino. A position sensor (so I use a GPS module. This GPS module must be Adafruit Ultimate GPS Data Acquisition Module (GPS Included)). A position storage (with an SD card that must work with an SPI link). A bluetooth interface. A GUI to visualize the route (using an Android tablet that is compatible with a bluetooth module).
you can advise me to use what as a component . because it's 3 components must be compatible with Arduino and an Android tablet IHM thanks to a Bluetooth module.
@@ElectroniClinic Hi! Could you post links for all the libraries you used? I'm encountering a problem for the SimpleTimer and LCD display. Thanks!
can you use a different version of nrf?, for example nrf24l01 with antenna
Thanks
You are welcome Gaurav.
Which is better? The one with the header or the one with node address?
Sir what is program for covering the maximum distance while using rf24networl library...
Thank you for the video that makes me can find idea for my thesis. I have a question, can the data be stored into database such as TinyDB and be visualize in some kind of apps like web apps or mobile apps?
of course you can.
hello, if between transmitter 1 and 2 if the frequency is different can the receiver receive?
Please answer the question about "void value not ignored as it ought to be" .done=radio.read(data,sizeof(data)); reciever code is no good with this error message

I used shift register 74HC165 to increase my push button switches, and 3 pins of Shift register (Load in Pin1, Clock in Pin2 and Serial out Pin9) are connected to arduino with wires and it's working ok. How is it possible to connect wirelessly 3 pins of Shift register to 3 or more arduino boards and achieve the same result with the use of NRF24L01? THANK YOU.
Is there anything specific to be done with the Esp32 DevKit V1 board, to use the nRF24L01+PA+LNA, because I've done it in several ways and didn't connect for anything?
Great lesson please can you do the same project using a PIR motion sensor with a siren at the reciever, thank you
ya, of course, I can. I added this to my list.

i like you video and presentation..
may i ask question can I use these method of programming using 7segment display??
Thank you. Ya you can use.
@@ElectroniClinic how would i code it because I've try many times and nothing happen.
Thank you for your tutorial. It was very helpful. I have one problem: my receiver is getting data from my 4 transmitters in strange intervals. I get data from transmitters 1-4 in a sequence like 111111222233232442444444444444441212123444. Can you help explain why this is happening? Thank you!
Hello! I want your help and guidance in one of my project, can you help me please
This is a nice project.how can i send the data collected by nrf reciever module via gsm module internet.thanks in advance.
this is quite simple, All you need define another serial port on the Arduino for the GSM module, and then all you need is to send that data to the gsm module. If you find this confusing, you can watch my videos on gsm module.
@@ElectroniClinic thanks
Where can i get the components list for this project?
good pls give me heart
you deserve it.

How can i read the address of direction for example node1 send a and the valué of sensor
This idea i will explain in the next video. It will be based on the two way communication. Any node will be able to communicate with any other node in the network.
Even if you watch this video, you will find, these nodes are assigned unique address, on the receiver side i am using if conditions to check form which transmitter i am receiving the data.
I want to make a remote car project, I've tried to communicate in bi- directions and it worked. but because of my situation i need 2 arduino nano in the car, so can nrf24 be used for 3 units to communicate in bi-directions ?
ya of course you can use. watch my other videos on nrf modules.
@@ElectroniClinic thank you very much sir, if i use 2 different microcontrollers is this not a problem? for example remote stm32f103c8 and remote car arduino nano
@@maulanawahyudi7127 ya, you can use. I did the same thing in my latest videos on Lora Sx1278 modules.
@@ElectroniClinic I have a problem, sir, when communicating in two directions using stm and arduino, where the feedback reading from the sensor in my car reads randomly even though I've used the same program on my arduino ide with my arduino nano. Please help me, what should i do ? Because my program works fine in arduino nano
Attention using modules produced by EBYTE, based on nrf24L01. From some time on they use a clone and not a true Nordic component, not compatible with previous modules. This has caused many problems on production based on this module! EBYTE does not admit this! Buy these modules from more reliable builders (or build it your own)
If i send data from multiple transmitters simultaneously that data gets garbled can u please help on this.
It's been 2 months since your question with no answers.
So I'm curious, have you figured this out?
I'm working on a project right now where I'll have up to 6 transmitters and 1 receiver. (well, there may be more than 1 receiver for a couple of different locations).
So I've been wondering the same thing.
I have no problems with one on one, but 6 to one, I'm not sure of how to do that either.
I don't know that if all 6 go into LISTEN mode and the receiver sends out a code to trigger one at a time. When the code, say, C1, C2, C3 etc is heard, then THAT module would SEND its data, then wait for a confirmation of receipt.
The other way I thought though, is since I'm using Nextion Enhanced displays for each Tx, they have RTC and what I thought was, MAYBE, I could have the Nextion, depending on the channel that the Arduino is configured for, it could tell the arduino to SEND at certain intervals, each device being at specific intervals.
Perhaps a 2 or 3 second difference.
Just ideas at this point.
I'm curious about something.
Is there any specific reason why you use those specific identifying codes,
231 and 434?
Is that significant for some reason?
Could one just use 0 and 1 or perhaps 0, 1, 2, 3, 4, 5, 6 to identify?
Where is the pipe⛲ disappears in the last sketches? 👲
Can you please give me code for f-22 plane for transmitter and receiver
