1. Kit Contents

• 1 x CC2650 SensorTag with enclosure

• 1 x CR2032 Battery

• Quick Start Guide

The RF board in this kit is FCC and IC certified and tested/complies with ETSI/R&TTE over temperature from 0 to +35°C1. The RF board has an integrated PCB antenna.

FCC/IC Regulatory Compliance FCC Part 15 Class A Compliant IC ICES-003 Class A Compliant

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 battery2 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,

• Ambient Light Sensor (OPT3001) from Texas Instruments

• Humidity Sensor (SHT21) from Sensirion,

• Pressure Sensor (BMP280) from Bosch,

• Accelerometer/Gyroscope (MPU-6500) from

Invensense,

• Reed Switch (MK24) from Meder

• Microphone (SPH0641) from Knowles

• Buzzer (HCS0503A) from Changzhou

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 reactivate advertising and turning on the SensorTag press the power button once more.

Operating temperature for CC2650 is -40° to 85°C

Maximum input voltage is 3.6V

The TI Bluetooth SensorTag app allows you to create your “own” app by selecting the different sensors you want to use.

When connected to the SensorTag click on the SensorTag tab to see readings from the sensors.

Turn on and off the sensors by selecting ‘Profiles’ in the bottom, left corner on iOS or click on ‘Services’ on Android. In the Profiles section on iOS it is possible to adjust the sensor data collection interval by moving the sliding bars, and select which axis to display for the multi-axis sensors. When you click ‘Back’ the TI Bluetooth SensorTag app will display the selected sensor data with the selected data interval.

Enable sensor information data by clicking the different sensors, this will also allow for a graph view of the sensor readings. The data collected in the graph view can then be sent to an e-mail address by clicking on the icon in the bottom left corner.

7. Using the app as an attribute and service explorer

You can use the Bluetooth SensorTag iOS read the services and attributes of any Bluetooth low energy enabled device.

can be downloaded at Google Play.

8. Using the SensorTag with the

BLE Device Monitor for Windows

Download and install TI’s BLE Device Monitor from: www.ti.com/sensortag. Please note that you also need a CC2540 USB dongle to use the BLE Device monitor.

The BLE Device Monitor allows you to discover, read and alter attributes on any BLE device. More detailed information about the BLE Device Monitor can be found at:

www.ti.com/sensortag

Note that BLE Device Monitor is currently only supported on Windows 7/XP.

9. Supported platforms

To use the SensorTag a Bluetooth 4.0 device is required and the API of the device must support the Bluetooth low energy API. Currently the following devices are supported:

• Android devices (supporting Bluetooth 4.0) running Android 4.3 or newer.

• iPhone 4S or newer

• iPad (3) or newer and iPad mini

• iPod Touch (5th generation)

• MacBook Air ( 2011 model and newer)

• MacBook Pro (2012 model and newer)

• Windows 7/XP PC with CC2540 USB

dongle connected using BLE Device Monitor. Part of TI BLE stack v1.30 and newer.
