I am new here and would like to receive your advice on the following:
For an art installation, I need to to send by radio ten integer values from a master laptop computer to 100 battery powered slave devices (basically a microcontroller + a DFPlayer module + a Radio module) that are going to be placed on the floor forming a 10 meters by 10 meters grid. The installation will be placed inside contemporary art museums which probably will have an iron and concrete structure and it is important to keep costs down.
I am thinking on using nRF24L01modules with integrated antena for the slave devices and a nRF24L01+ PA/LNA module with duck-antena for the master.
Will this set up work? any better ideas?
Thanks so much for your advice!
