Motion Sensor Plug-in
The motion sensor plug-in uses a web-camera to report on any sensed motion. To enable this kind of functionality, the motion sensor periodically takes pictures (using the web-cam) and compares them to determine if there is any significant motion sensed in the area viewed by the camera.





Noise Sensor Plug-in
The noise sensor plug-in uses a microphone to report on the sensed noise. To enable this kind of functionality, the noise sensor periodically captures the audio input from the microphone and performs a simple analysis of its input to characterize the noise in the environment as a percentage.



Bluetooth Sensor Plug-in
The Bluetooth sensor plug-in uses a hardware Bluetooth adapter to detect the active, neighboring Bluetooth devices, and generates events when this set changes.






RFID Sensor Plug-in
The RFID sensor plug-in uses a hardware RFID adaptor to detect nearby RFID tags.








Connectivity Sensor Plug-in
The Connectivity sensor plug-in checks if there is an active connection to internet.







Location-by-IP Sensor Plug-in
The Location-by-IP sensor plug-in computes your location based on your IP. Typically, this returns a high-level result (like for example the city/countr, e.g., "Nicosia/Cyprus").







Calendar Sensor Plug-in
The Calendar sensor plug-in communicates with the Google Calendar service and fetches events from your personal calendar. The event information includes "title", "start time", "stop time" and "location". The plug-in checks for new events every 1 minute. It also uses a dialog (javax.swing) when first started to ask the user to enter her/his user name and password.




WiFi-based Location Sensor Plug-in
Checks the ID of nearby WiFi routers (e.g., MAC address) in order to determine the location of the device.







GSM-based Location Sensor Plug-in
Uses the ID reported by nearby GSM cell towers to detect the location of the device.
