Has anyone on the team actually tested communications for the distances involved? That must be done as part of the decision for devices that will be used.
β projects β are about how you find out/research stuff and making you think . Itβs about a problem solving Exercise and not just making a device . How you go about it is where the marks are .
Get your options for rf and make a table of good points and bad based in what you want it to do.
From your list make a choice and why .
When you write it up , you include that reasoning - that is far far better than saying β I just asked someone β.
Yep, I agree with you especially testing rf stuff is new to me, I haven't done any rf range or rf barrier problems.
But as I mentioned I don't have a problem with the range since the distances are lower than 500m, so the nrf24L01 with the antenna should cover the area.
My concern is that I have to put the electronic stuff inside a metal box sealed to prevent dust and water. Also to secure the project from the students who might act un-responsibly and dismantle or abuse the electronic parts.
