That 100V LED driver is ringing alarm bells, what is it powered from? is it isolated?
Is the 24V power suppply isolated?
is the Pi connected to anything other than the arduino?
How are the the Pi and arduino powered?
What are the output characteristics of the PIR? is there anything to protect the arduino from overvoltage if the PIR loses it's ground connection?
