limit switch actuations being recorded

Projects General Guidance
1

Hi,

I am new to this Adruino eco system and am wondering if it will be a suitable platform for what I hope to do.

I would like to use limit switches to record actuations of a door opening. I would then like to wirelessly send that actuation data to a PC.

I imagine having a limit switch attached either wired or wirelessly to an Arduino and then the Arduino unit sending off a signal wirelessly to a PC interface that records the time and date of the actuation.

Please see attachment. The Ardunio is a receiver in my attachment.

Any feedback good or bad on my idea would be greatly appreciated. I can't find anything off the shelf to work with.

There are lots of wireless door chime type sensors.
Stick a light dependent resistor over the top of the LED indicator on the base unit. Measure the resistance using the Arduino and signal the computer via the USB serial port.

I believe you can use nrf24 wireless modules for wireless communication from multiple doors to one receiving arduino. Google some nrf24 projects. Each door gets an arduino, an nrf24 and a door chime/limit switch.

Thank you for taking the time, guys. I appreciate this information. will trial the modules you mentioned and see what the results will be.
