The BlueSentry data acquisition and control module contains an 8 channel 16 bit AD converter (TI ADS8344) that samples analog signals and converts them to a Bluetooth-enabled digital data stream.  The device also has two general purpose digital in/outputs and 2 FET power switches for controlling sensor power that can be configured over the same Bluetooth link using simple output commands.

It can be operated in many modes:

1.  BlueSentry can be connected using Serial Port Profile directly to Bluetooth clients, giving computers and PDAs the ability to directly obtain data from the sensors.

2.  Both the BluePort XP and FireFly serial adapters can be used to automatically connect to BlueSentry to enable serial controllers, PCs, and other clients which do not have built-in Bluetooth hardware.
