| - | ===== Data ===== | + | Connecting a personal medical sensor device to the Internet enables storing measurements over time (compared to a single measurement displayed on the device display). A connected sensor is thus more valuable than a stand-alone device. Connected sensors do exist, but are often quite expensive. On the other hand, Bluetooth modules and Bluetooth enabled Smartphones are readily available and can act as a cheap gateway to the Internet. |
