This is a prototype vision of how a future government service could work. It's not a real service yet, but we're exploring what it could look like. Your feedback will help shape the real service.

Smart Car Park IoT Walkthrough

Step-by-step guide to experiencing real-time car park occupancy monitoring with IoT sensors

Try IoT-Powered Car Park Management

10 minutes to see real-time car park occupancy data from IoT sensors

No deployment needed. View a CloudWatch dashboard showing live occupancy across 50 parking spaces with automated insights.
No technical knowledge required

This walkthrough guides you through viewing a real-time dashboard powered by IoT sensors. Perfect for facilities managers, smart city teams, and anyone evaluating IoT for car park management or broader smart city initiatives.

What you'll do

In this 10-minute walkthrough, you'll:

  1. Access the CloudWatch dashboard - Find your deployed IoT monitoring dashboard (2 minutes)
  2. View real-time occupancy data - See live metrics across 3 car park zones (2 minutes)
  3. Understand the IoT data flow - Learn how sensor readings become dashboard insights (3 minutes)
  4. Explore occupancy trends & ROI - Analyze patterns and calculate business value (3 minutes)

Before you start

Important You must have already deployed the Smart Car Park scenario to your Innovation Sandbox account.

Deploy the Smart Car Park scenario if you haven't already. Deployment takes 5-7 minutes.

IoT sensor data check

Ready Sample data is pre-loaded and ready to use.

What you'll learn

For facilities managers

  • How IoT sensors detect vehicle presence
  • Real-time visibility across all car park zones
  • Automated alerts for high occupancy or sensor failures
  • Historical patterns showing peak vs off-peak usage
  • Elimination of manual space counting

For smart city teams

  • Revenue increase from improved occupancy (60% to 85%)
  • Operational cost savings (£9.75K/year eliminated)
  • ROI calculation and payback period
  • Scalability to other IoT use cases
  • Foundation for smart city strategy

The car park you'll monitor

We've simulated a typical council multi-storey car park with IoT sensors:

50 Total Spaces
3 Zones/Floors
50 IoT Sensors
1000 Data Points

How IoT sensors work

Each parking space has an ultrasonic sensor that detects vehicle presence:

1

Sensor detects vehicle

Ultrasonic distance measurement determines if space is occupied

2

Data sent to AWS IoT Core

Sensor publishes MQTT message with occupancy state

3

Lambda processes reading

Validates data, stores history, publishes metrics

4

CloudWatch displays dashboard

Real-time metrics visible in your browser

AWS services used: IoT Core (message broker), Lambda (processing), DynamoDB (history storage), CloudWatch (visualization + alerts)

The wow moment

When you open the CloudWatch dashboard, you'll see:

  • Live occupancy updates - Dashboard refreshes every 10 seconds automatically
  • Multi-zone visibility - See all 3 floors at once (impossible with manual counting)
  • 24-hour historical trends - Identify peak hours and quiet periods instantly
  • Automated alerts - Get notified when occupancy reaches thresholds

All powered by 50 IoT sensors collecting data every 2 minutes. Zero manual effort. No clipboards. No spreadsheets. No outdated information.

Think about your council car parks

How many car parks does your council manage?

Consider the impact per 50-space car park:

Manual counting eliminated
Save £9,750/year in labor costs
Occupancy improvement
From 60% to 85% = £16,250 additional revenue/year
Total annual benefit
£26,000 per car park
AWS annual cost
£145/year (IoT Core, Lambda, DynamoDB, CloudWatch)
Net ROI
178:1 return - payback in 2 days

Committee language: "IoT sensors transform car park management from reactive to proactive. Real-time occupancy data increases revenue by £16K annually while eliminating manual counting costs of £9.75K. Total annual benefit of £26K against AWS costs of £145 delivers a 178:1 return on investment, with payback achieved in just 2 days."
