Powered by batteries or any 5-25VDC source, BlueSentry can acquire up to eight 0-5V inputs at high (16bit) resolution and send this information to Bluetooth-enabled clients, Lans or the internet
BlueSentry AD is a complete, wireless enabled data acquisition and output control unit, measuring only 7.5x2.5cm in size.
Powered by AA batteries, car batteries, or any 5-25VDC source, BlueSentry can acquire up to eight 0-5V inputs at high (16bit) resolution and send this information to Bluetooth- enabled clients, Lans or anywhere on the internet.
The device can also be wirelessly linked to a paired output module, BlueSentry-DA, to replicate four analogue channels at a distance of up to 100m.
Typical applications for the device include process control monitoring, motion detection, temperature/humidity sensing, stress and strain gauges, fluid and gas metering, and scores of other applications where physical cabling is not possible or desirable.
"We have a wireless application where we are using the BlueSentry sensor adapter to record pressure and supply an excitation voltage to our pressure transducer," said Shabbir Ezzi, a software and project engineer at Koehler Instruments.
"We have a battery power source, so the 'sleep' feature allows us to monitor for a longer period of time without replacing batteries".
Brief specification: BlueSentry devices can be operated in two modes:.
BlueSentry AD can be connected using serial port profile directly to Bluetooth clients, giving computers and PDAs the ability to directly obtain data from the sensors.
In access point mode, A Blue-Line (additional product) access point can acquire, store, and display data over a Lan or the internet from multiple BlueSentry-ADs, and can remote control multiple BlueSentry-DAs as well.
Key features:.
Class I Bluetooth - radio for long-range operation, up to 100m.
Sleep mode (4ma) while still discovererable/connectable.
External trigger activation.
Up to 1khz data rates(binary mode, one channel).
Selectable one to eight channels of sampling.
Selectable data capture rates, from 1Hz to 1Khz.
