Hello there
I need to make a lot of sensors to use in Predictive Maintenance.
Is possible assemble a NANO with a 2 vibration sensor, 10 Type J TC Reader, 2 Digital I/O, 1 Gas sensor, a flame detector and hall effect sensor in a single case, connect this data wifi with a main PC?
The case of course have the wiring connectors required and only have 110 VCA as power source, have to make up to 75 of this sensors cases and install in several points, integrate all those signaling and data in a PC computer, is possible?
Thanks.
Hi @alendi.
If you want Wi-Fi network connectivity, the classic Nano board is not the best choice. You can consider the newer boards offered by Arduino in the same "Nano" form factor that have Wi-Fi communication capability:

Hi Ptillisch
Thanks, but what's tha hardware that I have to aqquire for it?
Ah, someone wants a free system design done for them!

You should know that before you start building. Research. This does not sound like an Etsy project.
You will need to know the voltage requirement and number of I/O pins for each device. You get those by searching for "(device) datasheet" or "(device) specification." Also, define "2 Digital I/O."
Start by picking another board. Although I don't have experience with them, consider an ESP32. At least you have your WiFi requirements covered.
Hi, @alendi
Can you please post links to data/specs of these items?
What is the overall project?
What environment?
Is it an industrial installation?
Thanks.. Tom.. 
Sort of; the WiFi will require an additional ESP module or a different Arduino board, though.
But in an industrial context, why not just use a PLC like everyone else?
please confirm that you are able to force the maintenance problems for testing of your system.
Hello alendi
Post the data sheets of a.m. sensors.
Should the Arduino only collect the data or should it be pre-processed before it is sent via WiFi?
