I am trying to create a device with a small sensor that will send a signal to a wireless alarm if the proximity is encroached by another sensor for a certain amount of time. ie if sensor 1 gets within 10 inches of sensor 2 for greater than 5 secs, the wireless alarm will be activated.
At least 1 of the sensors need to be pretty small (less than 8mm) and the other needs to be relatively small (less than 1 inch)
