[19p-W631-6] Sensors bring IoT projects and environment measurements
Keywords:sensor,Internet of thing,cyber physics society
IoT: Internet of thing is known as one of the next-generation technical revolutions. Sensor is the device that provides effective data by connecting to Internet. Physics or chemistry phenomenon is converted to voltages by sensors and a signal processing circuits. After digitization and microcomputer processing, the data are sent into a cloud by wireless communication. The data give users useful information, and feedbacks for the devices or social movements. These flows are called cyber physics society or industrial internet. In this lecture, I introduce the development of Smart phone connected radiation and the PM2.5 measurement system. Wi-Fi directly connected environmental measurement system driven by small solar cell battery is also explained. Then, the application and influence to social movement are discussed.
