  • Additionally, smart binsalert authorities for timely waste collection, and disaster monitoring sensors provide early warnings for floods and earthquakes.
  • g., The city of Jaipurhas launched the “Jaipur Smart City” project, featuring smart lighting systems and intelligent traffic management solutions.
• Smart Homes: Automated lighting and appliances, such as smart thermostatsand lighting systems, adjust based on usage to save energy, while IoT-enabled security devices—including cameras, door locks, and motion sensors—offer real-time alerts and remote monitoring.
  • g., Google’s Nest Thermostatuses AI, sensors, and machine learning to optimize home heating and cooling for energy efficiency, cost savings, and convenience.
• Healthcare:Remote patient monitoring uses IoT-enabled medical devices (glucose monitors) to send real-time data to doctors, and emergency alert systems notify services if a patient is in distress.
  • Wearable deviceslike smartwatches (e.g., Apple Watch) monitor heart rate, and sleep cycle.
• Smarter Transportation:Fleet tracking helps logistics companies monitor vehicle health, fuel use, and driver behavior, while smart parking sensors guide drivers to open spots, easing congestion.
