sensors are chosen to be small, energy efficient
and low cost surface mount devices. The
sensors use I2C interface and are connected to
the same interface bus with separate enable
signals. To minimize current consumption all
sensors are by default disabled and they are in
sleep mode between measurements. Each
sensor can be enabled and read individually. The
SensorTag includes the following sensors:
IR Temperature Sensor (TMP006) from
Texas Instruments,
http://www.ti.com/product/tmp006

5. Connecting to a Bluetooth 4.0
enabled iDevice
The SensorTag can communicate with any
Bluetooth 4.0 enabled devices, for instance a
smart phone or a tablet.
For a Bluetooth 4.0 iOS Device to communicate
with the SensorTag, Bluetooth needs to be
turned on and the SensorTag needs to be
advertising. The SensorTag can enable and
disable advertising by pushing the side button.
When the SensorTag is advertising the green
LED (D1) is blinking. It might be hard to see the
blinking LED when the SensorTag is fully
assembled.
Currently the TI Bluetooth SensorTag app is only
supported for Bluetooth 4.0 enabled iOS devices
(iPhone 4S, iPhone 5, iPod Touch and the new
iPad). There is currently no common Bluetooth
low energy Application Program Interface (API)
for Android devices available.
Download the TI Bluetooth SensorTag app from
Apple‟s App Store:
Start the TI Bluetooth SensorTag app. When the
app is launched it will search for all Bluetooth low
energy devices in the area. Enable advertising by
clicking on the side button. The SensorTag icon
should
appear
indicating
successful
connection.
Or search for SensorTag on App Store.
If no Bluetooth 4.0 devices are detected by the
