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.

One of the best learning channels on the YouTube

[shingabiss]

This is an excellent, well made tutorial! I have been searching for what this presentation covers for days! Thanks for making this!

[tanjiannan]

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.

[shakirmohdnoor]

Which is better? The one with the header or the one with node address?

[webslinger]

Finally found a very good tutorial for multiple nrf network data communication. Thank you!

[rafaelrpa]

Este canal é fantástico! Tem me ajudado muito no meu desenvolvimento.

[shakirmohdnoor]

Thank you. I am studying and researching to make my final year project. Where can I contact with u to learn more about this wireless technology?. Pls respond. I really need your help

[sylgonjaysanoy]

i like you video and presentation..

may i ask question can I use these method of programming using 7segment display??

[zainulmuttaqinalghiffari]

can you use a different version of nrf?, for example nrf24l01 with antenna

[rafaelrpa]

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?

[davidverheyen]

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.

[xrphobby]

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.

[jman]

Schematic shows only one capacitor, but PCB shows 4 (across NRF24L01 + and -). What are the other ones for?

[samrogers]

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

[basavarajd]

Sir what is program for covering the maximum distance while using rf24networl library...

[abangtoyib]

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?

[inspirationalwords]

Great lesson please can you do the same project using a PIR motion sensor with a siren at the reciever, thank you

[enzoternavasio]

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)

[epanudin]

hello, if between transmitter 1 and 2 if the frequency is different can the receiver receive?

[daverieder]

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 Can you help explain why this is happening? Thank you!
