AI is the city’s brain and IoT is the city’s sensors and actuators. The brain analyzes the information from eyes, ears, taste, smell, and touch, and notify hand to do and way to walk. IoT is those sensors and actuators in the smart city.

This book explores an IoT concept is IoT = Sensor/Actuator + Edge Processor, a sensor is a very important component of IoT, we introduce a “Smell” sensor design to explain the concept, and we call this AI smell sensor a name “Aromathpia”, it is a smell sensor with artificial intelligence, and we put in on an autonomous car, thus the car could explore the “smell” in the city, this concept in this book become a backbone to explain IoT in smart city.
