 		 #169958 - Inductive proximity switch
Responding to: ???'s previous message
I am using inductive proximity switch. This switch is drive optocoupler and optocoupler drrive drive external interrupt pin. It is working but randomly mc receive extra interrupt. Can winter session effect on the circuit.

         Looked at the signal?            01/01/70 00:00      
            air humidity and external interrupt pin            01/01/70 00:00      
               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      
      using new proximity switch            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      
      Not necessarily true            01/01/70 00:00
