Hi, I am a new member and I will be grateful for any guidance. I have been reading on my requirements but the first few steps I have found are usually above my level of understanding and I come to a stop rather suddenly. I have been reading about IoT and in particular boards with wifi such as Pi, Arduino, NodeMCU, Zigbee, and the like to help me with an issue.

I need to record a signal and time stamp it. Let's assume the signal is something like an on / off recording, something like a simple limit switch. I want that physically connected to a board (device) that is small and is battery operated. This board needs to send a wifi signal up to preferably 100m to a wifi / ethernet switch by IP address. The switch is connected to a PC. The PC has a small program that captures the time stamp.I may have multiple limit switches and boards which all connect to the same switch and all have their time stamps recorded.

Some important points:
• I want the boards to be small; smaller the better. I will preferably like to have them covered in heat shrink wrap or in a plastic / perspex case once connected to the switch / actuator.

What is the timing of the input signals?

Time resolution?
Frequency?

frequency maybe maximum every 20 seconds. time resolution within a second is fine.

I have just ordered one of these http://www.ebyte.com/en/product-view-news.aspx?id=176 but the basic question like whether I can connect a simple limit style on/off switch to this and have it send a signal is something I just cannot find. Or do I need to add this to a board?

I have also ordered this https://www.lazada.co.th/-i150410834-s175568672.html?urlFlag=true&mp=1

These basic questions seem to just be assumed even in the most basic tutorials I can find. It is hard to get a starting point.
