Zusammenfassung
Complex event processing systems have gained importance since recent developments in communication
and integrated circuits technologies. Developers can easily develop many smart space systems by
connecting various sensors to an Arduino as an internet of thing device. These systems are useful for many
places such as factories, greenhouses (plant house) and smart-homes. Especially in plant houses when the
desired humidity, temperature, light and soil moisture drops the certain level, the users should be notified
through their smartphones. The sensor information is sent to a central server over the internet via an
access point. The collected sensor data needs to be processed online to check whether an event is occurred
or not. The event processing system based on a complex event processing tool is created on the central
server. It is also an important issue to inform mobile users whenever an event occurs. A publish-subscribe
event based system is implemented on the central server. A mobile user is subscribed to the desired event
topic. When an event occurred, which is related with a specific topic, an alarm notification is sent to the
mobile users about the event information so as to take necessary precautions.
