The document discusses using TI SensorTags and a BeagleBone Black to create Internet of Things applications without wiring. It describes using the sensors on the SensorTag, including temperature, light, motion and magnetic sensors, to monitor and visualize the status of a toilet remotely. The proposed architecture involves connecting the SensorTag to a BeagleBone Black via Bluetooth and sending the sensor data over a Bluetooth WebSocket connection. Examples of other potential applications mentioned are a security alarm system and elderly monitoring system. The BeagleBone Black is recommended due to its open source hardware, pre-installed operating system and IDE, and ability to run programs without Unix commands.
