Project Description:
********************
Before, we are going to make a wireless sensor network using multiple NRF24L01 modules; you will need to learn some basics which I have already explained in my previous tutorials. To keep things simple and easy to follow, I started with only two NRF24L01 modules.
In my first tutorial, I explained how to make a long-range 12V battery voltage monitoring system using a pair of NRF24L01 Transceiver modules with the HC05 Bluetooth module. I was able to monitor the voltage of a 12V battery using my android cell phone application.
Things get a little complicated when it comes to multiple sensors connected with multiple NRF24L01 modules. So, I decided to make a third tutorial in which I explained the very basics explaining
1. The maximum number of NRF24L01 modules that can be used in a wireless sensor network.
2. How to monitor multiple sensors connected with multiple transmitters. This was based on one-way communication. The two transmitters were communicating with a single receiver. D1 is the value coming from the Transmitter number1 and D2 is the value coming from the transmitter number2. In this tutorial, I also explained how you can increase the number of transmitters.
So, I highly recommend first watch my previous three tutorials, and then you can resume from here.
To make a Wireless Sensor Network using Multiple NRF24L01 Transceiver modules, each Sensor Node in the Wireless Sensor Network should be able to send and receive data from any other Sensor Node in the Wireless network. At any Sensor Node in the wireless network, you should know exactly from which Sensor Node you are receiving the data. Unique addresses are assigned to all the Sensor nodes in the wireless sensor network which are used to identify the Sensor nodes.

Great
Great Sir 🤩🤩
Nice, you gave me some ideas.... well done !
👏👏👏
amazing!
I am the first
Thanks!
Sorry, but please fix your posted code for the last iteration. Been trying to follow but having problems understanding your code from your website.
Hy bro make a wireless camera based on nrf24lo module
Sure, i will take a look...
Thanks bro
saya juga berpikir ide ini ,
Hey dude! Pls make an esc for a brushed dc motor
Thanks for this tutorial, am almost working on something related to this...I need help please. Hello sir, I'm working on a project called wireless notice board, using aurdino, two Xbee series 2c, 8*8 dot matrix board (4 in 1) for the display. The aim of the project is to wirelessly update the message scrolling on the dot matrix board using the Xbee. One Xbee is connected to the Arduino, the matrix board is also connected to the Arduino (I don't know if my connection is Correct) then the Arduino is connected to the laptop through USB, the second xbee is connected to another USB port. I use the XCTU software to check if the connections between the two Xbee is okay, I can send a message wirelessly to the other Xbee and vice versa... to command it to update the matrix board is my problem here please help me guys. I want to summit the project in school next week
Is it possible to use 2 transceivers to operate switches from both ends?
Hi I have Arduino Uno with 3 pins connected to Max7219 to display 7-segment LED. How is it possible to send data to another 4 Arduino Uno with NRF214 so that I will have exactly the same display on all my 7-segment LEDs. Thank you.
How about max range if we are using 2MBPS transfer rate sir?
At level 1 I want to expand a total of 6 nodes. But limited to node05. The next node6 is not receiving any data.
I think each parent node can only have 5 children. In the diagram in the video, this is shown at levels 2 and 3, but I think there is a mistake at level 1 showing 6 children.
Thinking about it again, each NRF2401L board can communicate with upto 6 other boards. So, in levels 2 and 3, that would be 5 children and one parent. But the base NRF2401L at the top of the tree has no parent, so should be able to communicate with 6 children?? Clarification required!
