CC2650 SensorTag Quick Start Guide
Opening the Box and Using the SensorTag
The SensorTag simplifies development of Bluetooth low energy sensor applications. It allows app developers to quickly and easy write smart phone apps for
Bluetooth low energy accessories without any embedded hardware or software development.

Caution! Dispose the battery properly
and keep out of reach of children. If
swallowed, contact a physician
immediately.
2. Assembly of the SensorTag
Insert the battery
2
in the battery connector and
place the printed circuit board in the black plastic
cover with the battery facing down.
Note that when inserting the battery for the first
time, the PCB contact point surface may have a
thin layer of solder residue that can prevent
contact with the battery. Remove and insert the
battery a few times to power the SensorTag.
Caution! The kit contains ESD sensitive
components. Handle with care to prevent
permanent damage.
Add the transparent plastic cover to close the
inner hard plastic pieces. Complete the assembly
of the SensorTag by adding the red plastic cover.
3. Sensors
The SensorTag is fitted with several sensors and
all sensors are chosen to be small, energy
efficient and low cost surface mount devices. The
main communication interface with the sensors
are two separate I2C interface, one for the low
power sensors and one for high power sensors
(accelerometer/gyroscope). To minimize total
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
• Ambient Light Sensor (OPT3001) from
Texas Instruments
• Humidity Sensor (SHT21) from Sensirion,
• http://www.sensirion.com/en/products/humidi
ty-temperature/humidity-sensor-sht21/
• Pressure Sensor (BMP280) from Bosch,
• Accelerometer/Gyroscope (MPU-6500) from
Invensense,
• Reed Switch (MK24) from Meder
• Microphone (SPH0641) from Knowles
• Buzzer (HCS0503A) from Changzhou
Tianyin Electrical Appliance Co.
4. Downloading the SensorTag
app
The SensorTag can communicate with any
Bluetooth 4.0 enabled devices, for instance a
smart phone or a tablet.
The Bluetooth SensorTag app is supported for
both Bluetooth 4.0 enabled iOS devices and
Bluetooth 4.0 supported Android devices running
Android 4.3.
Download the TI Bluetooth iOS SensorTag app
from Apple’s App Store:
Or search for SensorTag on App Store.
Download the TI Bluetooth Android SensorTag
app from http://www.ti.com/tool/sensortag-sw:
5. Connecting to a Bluetooth 4.0
enabled device
For a Bluetooth 4.0 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 power button (see picture above).
When the SensorTag is advertising the red LED
will blink.
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 power button. The SensorTag
icon should appear indicating a successful
connection.
If no Bluetooth 4.0 devices are detected by the
SensorTag within 2 minutes, advertising will stop
and the SensorTag will go back to sleep. To re-
activate advertising and turning on the
SensorTag press the power button once more.
