How It Works
These wearables are equipped with a variety of sensors — heart rate monitors, accelerometers, temperature sensors, and more. When these sensors detect irregularities, they trigger an alert system. Modern wearables are often paired with smartphones via Bluetooth. In case of a detected emergency, the paired smartphone can automatically send a distress signal with the user’s location to designated emergency contacts or services.
3. Intelligent Public Transport:
Gone are the days of waiting endlessly at the bus stop, unaware of your bus’s whereabouts. IoT-powered public transport systems offer real-time tracking, providing precise timings and routes on your smartphone. This also enables transport authorities to swiftly address delays, reroute vehicles during heavy traffic, and ensure seamless connectivity. Passengers can thus enjoy a punctual, reliable, and efficient commuting experience.
How It Works
Buses, trams, and trains are fitted with GPS devices and other sensors. These continuously send their locations and operational statuses to a centralized monitoring system. Transit apps access this real-time data to inform users about vehicle positions, expected arrival times, and potential delays. Simultaneously, transit control centers can proactively manage the fleet for optimal service.
4. Connected Utility Monitoring
Imagine understanding your household’s water and electricity consumption patterns in real-time. With IoT-connected utility monitors, consumers can track daily, weekly, or monthly usage. This fosters conscious consumption, leading to cost savings and environmental conservation. On a broader scale, it equips city administrations with insights to manage utilities more effectively and address discrepancies instantly.
How It Works
Household utility systems are connected to IoT devices that measure consumption rates. This data is sent to a centralized cloud server. Users can then access this data through apps or online dashboards, which display consumption metrics in user-friendly charts and graphs. Alerts can be set for thresholds, promoting proactive resource management.
5. Air Quality Monitoring
Breathing clean air is a fundamental right. But with rising urban pollution, how do you ensure it? IoT-enabled air quality monitors dispersed across cities offer real-time insights into pollutant levels. Residents can check air quality indices before stepping out, especially beneficial for individuals with respiratory conditions. Moreover, this data equips city officials to address pollution hotspots and implement timely interventions.
How It Works
IoT sensors capable of detecting various pollutants are strategically placed across the city. These sensors measure pollutant concentrations and send this data to a centralized system at regular intervals. Mobile apps or websites access this data, providing residents with real-time air quality indices. When certain thresholds are crossed, the system can even trigger public warnings or advisories.
6. Smart Grids for Electricity
Traditional electrical grids operate in silence. But what if they could communicate? Smart grids, fortified with IoT tech, engage in a dynamic dialogue with both power producers and consumers. They can self-detect outages or malfunctions, making restoration faster. Consumers enjoy a more reliable power supply, and with two-way feedback mechanisms, they can even sell excess energy (like from solar panels) back to the grid.
How It Works
Smart grids use advanced metering infrastructure (AMI) that continuously records and communicates electricity consumption data. Besides, the grid can self-monitor its health. When an outage or irregularity is detected, the grid communicates this to the central control and possibly even reroutes power automatically to minimize downtime.
7. Automated Public Services
The modern city resident desires swift and efficient public services. By incorporating IoT into public infrastructures like libraries, residents can enjoy enhanced experiences. Picture this: you’re looking for a book, and instead of wandering through aisles, an automated system guides you directly to its location. This streamlined service reduces waiting times, improves resource utilization, and fosters a more engaged civic community.
How It Works
Public services are integrated with IoT devices. In the library example, books might have RFID tags, and libraries would have RFID readers. When a user searches for a specific book, the system scans the library using the readers, locates the book, and then guides the user using digital maps or signals.
The Impact on Sustainable Development
Let’s explore the multifaceted impact they’re having on sustainable city development.
