απόστασης (ultrasonic) εγκατεστημένος πάνω στο Arduino. Η λειτουργία αυτού βασίζεται στη
μέτρηση της απόστασης από τον κόμβο μέχρι κάποιο αντικείμενο (αυτοκίνητο) που εμποδίζει τη θέση του parking
και την εξαγωγή της κατάσταασης της αυτής της θέσης στη σειριακή θύρα του Arduino.< / p >

της θέσης του parking για το οποίο είναι υπεύθυνος. Με κόκκινο χαρακτηρίζεται η θέση που είναι
δεσμευμένη από ένα όχημα και με μπλε η ελεύθερη θέση, όπως φαίνεται στις παραπάνω εικόνες.< / p >

και την κατάσταση του parking, κωδικοποιημένα με τον διαχωριστή "#". Για την κατάσταση του parking ορίζουμε
με "1" ότι η θέση είναι ελεύθεση και με "0" ότι η θέση είναι δεσμευμένη. Ο έλεγχος του sensor γίνεται κάθε
500ms. Η έξοδος στη σειριακή γίνεται με την μορφή ενός string< / p >

λαμβάνεται και αποθηκεύεται στον "Gateway" κόμβο.< / p >
