Responding to: ???'s previous message
Air humidity can affect some types of sensors.

Have you looked with an oscilloscope what the signal looks like on the interrupt input when the metal piece is just on the limit of detection?

               No, the interrupt line isn't affected by air humidity            01/01/70 00:00      
                  air humidity can affect - also temperature, etc            01/01/70 00:00      
   May be the proximity switch not working properly            01/01/70 00:00      
      Indication is not proof            01/01/70 00:00

         Are you using it correctly?            01/01/70 00:00      
            i am using proximity switch correctly            01/01/70 00:00
