Abstract
Bluemix Parking Meter is an open-source Internet of Things (IoT) project. IoT Smart Parking Metering system with IBM Bluemix & PubNub. This project demonstrates how we can build an application server on IBM Bluemix that allows users to reserve parking spaces and automatically handles their parking bills as well. The Hardware for this is based on Arduino YUN which can control a set of HC-SR04 ultrasonic sensors, to detect the availability of a parking slot and update this information on a mobile app using the PubNub's realtime data stream network. It is built using Java. The complete source code is publicly available on GitHub under the MIT License, making it a useful reference for students building an Internet of Things (IoT) mini project or final-year project.
1. Introduction
This project demonstrates how we can build an application server on IBM Bluemix that allows users to reserve parking spaces and automatically handles their parking bills as well. The Hardware for this is based on Arduino YUN which can control a set of HC-SR04 ultrasonic sensors, to detect the availability of a parking slot and update this information on a mobile app using the PubNub's realtime data stream network.
This application is assumed to be installed in a public parking space where each parking space is monitored using a HC-SR04 ultrsonic sensor connected to Arduino YUN board.
1) Parking Management Server - This is the application server written in Python which manages the parking reservations, billing and broadcasts parking status updates to all Apps. For hosting this on IBM Bluemix, refer the "APPLICATION SERVER HOSTING" section below.
2. Objective
IoT Smart Parking Metering system with IBM Bluemix & PubNub
This project demonstrates how Java can be applied to a real-world Internet of Things (IoT) problem.

8. Viva / Review Questions
Common questions examiners ask for projects in this domain.
- Which microcontroller / board and sensors are used and why?
- How does the device send data (Wi-Fi, MQTT, HTTP, Bluetooth)?
- Where is the sensor data stored and visualised?
- How is power consumption managed?
- How would you secure the device and its communication?
