For an industrial application, which is better?
-We want to control relays to control a line production in an automotive industry.
-We want to monitor the producction (how many boxes were produced)
We want stability and fine data
Particle is excellent for Industrial IoT.
The modules are fantastic, the service is responsive, and the community is active.
You can even buy the modules wholesale.
I would recommend the Photon, but you can also buy the P0 and P1 modules on their own so you can create your own PCB.
