I have a tunnel system which has several bulkheads which close when I issue their closure through a PDA, although I want a alarm that detects intruders and send the signal to the master computer, I can handle the rednet stuff if someone can help me code a device to check who the sensor detects, I'm playing the mindcrack crackpack and I think the sensor is from opens peripherals addon... I don't know where to start


I understand this isn't somewhere for people to give code but your time will be greatly appreciated.

You'll first want to determine how to use the peripheral. This guide should teach you how to figure that out.

If the device is a recentish OpenPeripheral block, you may also be able to get further information about the commands it grants you by entering into the prompt:

openp/docs <side> <methodname>

... That doesnt help, I know how to use peripherals its just the tables and stuff i dont understand

[Bomb Bloke]

Righto then.

You can use sensor.getPlayerNames() (Ofcourse sensor. would be your wrap for the peripheral)
This will reutrn a table of all people withing sensor range. Then this way you can loop through them:

 for i,player in pairs(sensor.getPlayerNames) do
 
end

Then to check whether or not he is an intruder you could set up a whitelist using a table

whitelist={
["playerName"]=true,
["anoterName"]=true,
["nameyName"]=true,
}
function checkPlayers()
 for id,player in pairs(sensor.getPlayerNames) do
  if not whitelist[player] then
   --Your code to sound the alarm
  end
 end
end
