It allows app developers to quickly and easy write smart phone apps for Bluetooth low energy accessories without any embedded hardware or software development. www.ti.com/SensorTag 1. Kit Contents SensorTag 1x CR2032 Battery Documentation The RF boards in this kit are FCC and IC certified and tested/complies with ETSI/R&TTE over temperature from 0 to +35°C1. The RF board have integrated PCB antenna. Caution! Dispose the battery properly and keep out of reach of children. If swallowed, contact a physician immediately. Caution! The kit contains ESD sensitive components. Handle with care to prevent permanent damage. 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 has a thin layer of solder residue that may prevent contact with the battery. Remove and insert the battery a few times to power the SensorTag. Push the side button to check if the battery is correctly inserted. When the button is pushed the LED marked D1 should start to blink. 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 six sensors and all 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 Humidity Sensor (SHT21) from Sensirion, http://www.sensirion.com/en/products/humidity-temperature/humidity-sensor-sht21/ Pressure Sensor (T5400) from Epcos, http://www.epcos.com/inf/57/ds/T5400.pdf Accelerometer (KXTJ9) from Kionix, http://www.kionix.com/accelerometers/kxtj9 Gyroscope (IMU-3000) from InvenSense, http://www.invensense.com/mems/gyro/imu3000.html Magnetometer (MAG3110) from Freescale, http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=MAG3110 4. Downloading the app from App Store The SensorTag can communicate with any Bluetooth 4.0 enabled devices, for instance a smart phone or a tablet. 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: Or search for SensorTag on App Store. 5. Connecting to a Bluetooth 4.0 enabled iDevice 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. 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 a successful connection. If no Bluetooth 4.0 devices are detected by the SensorTag within 30 seconds, advertising will stop and the SensorTag will go back to sleep. To re-activate advertising and turning on the SensorTag press the side button once more. 1 Operating temperature for CC2541 is -40 to 85C 2 Maximum input voltage is 3.6V Side Button
