The uWatch Cube has Bluetooth Low Energy (BLE) embedded. We have implemented two forms of BLE.
Alerts from External Sensors
The first is the ability to accept alerts from a BLE device. For instance, a simple float mechanism could be used in the bilges of a boat. When it floats it sends a message via BLE to your Cube which raises an alert.
Other remote sensors could be flood, smoke or fire sensors; sensors on traps; or sensors used in a care environment using pressure pads or wearable devices.
Trigger External Devices
The second type is where an alert triggers a BLE output from your Cube. For instance, a PIR trigger could cause a BLE output to switch on a light before taking a picture. So you would get an alert followed by a second alert with the picture. We have found that pictures with even a small amount of light at night are better than night-vision cameras.
Other triggers could set off a siren or a recorded message; could release a trap, or in a care environment, could open a door.
Applications Tailored to Specific Markets
Our aim at uWatch is to provide the interfaces so that others can develop applications focused on their particular needs and markets. For instance a marine agent might take the float switch idea and develop it, or a group interested in trapping animals might develop an application that releases the trap if the wrong animal is caught.
