碩士 === 華梵大學 === 電子工程學系碩士班 === 106 === In this thesis we propose an IoT application architecture that is based on the integrated heterogeneous wireless network of WSN (Wireless Sensor Network) ,Wi-Fi and GPRS (General Packet Radio Service). Besides basic wireless sensors on detecting temperature and humidity, there are two types of CO2 sensors adopted to monitor the environment. The comparisons between those CO2 sensors in different specifications are studied to help components utilization. In constructing our network, ZigBee networks are deployed at sensor field to collect sensor data via short distance wireless transmissions among nodes in topology. In connecting to internet cloud, ZigBee network is then bridged to Wi-Fi or GPRS network to let the collected data forward to internet IoT-server that offers data storage and query. Users and application objects are then allowed to monitor sensor nodes by querying the IoT-server to get data. In applications, possible controls are replied to the sensor node when some criterions meet,. Therefore IoT relationship is established between sensor nodes and remote objects.
