Abstract
The purpose of this diploma thesis is the development of a complete wireless Condition Monitoring Service which can be used to monitor critical parameters for the proper operation of a system. The Service is developed using a top-down approach, starting from the system specification and finally resulting in the physical implementation. The Service consists of two fundamental components: a coin-sized sensor with wireless connectivity supplying the data, and a client application running on a mobile device.
For wireless connectivity, we choose Bluetooth Low Energy (BLE), an efficient, robust, low-power WPAN technology. BLE provides an open-minded and developer-oriented approach to the use of its specification for application development, entrusting the developer with wide aspects of the service implementation. For the client device, an Android application is developed, and great care is taken in order to provide a user-friendly GUI experience.
