Watson IoT Platform - Node-RED - TIセンサータグを使う

初めてWatson IoT Platformを使ってみよう、というかたのためのガイドです。
[Watson IoT Platformを使ってみる](http://qiita.com/egplnt/items/af867711a7191923b2ff)でIoTアプリを準備しました。

#TI(テキサス・インスツルメンツ社)製のセンサータグCC2650を使います
1. スマートフォンのAppStore(iPhone)/GooglePlay(Android）で「TI SensorTag」を検索してインストールします。

2. TIアプリを起動したら、TIセンサータグCC2650の側面の正方形のスイッチを押します。反対側に長方形のスイッチがあるのでややこしいです。
3. スマートフォンのアプリでセンタータグが認識されます。

4. 「Sensor View」を選択するとセンタータグとスマホの間でペアリングが行われ、センサーデータの送受信が始まります。

5. 画面に表示されている赤いセンタータグのアイコンをクリックすると、センタータグの詳細情報が表示され、英数字１２桁のセンサータグのデバイスIDが表示されるので書きとめておきます。
6. 「Cloud View」の画面で右側のスイッチをスライドすると、雲との間で送信を表す赤い両方向矢印が点滅しはじめ、クラウドへのセンサーデータ送信が始まります。

7. Node-REDのIoTアプリを開きます。
8. IoTフローの左端の青い「IBM IoT App In」ノードをダブルクリックで開き、前項で書きとめた英数字１２桁のデバイスIDを指定し、「OK」で保存します。
9. 画面右上の赤い「Deploy」ボタンを押してクラウド上のアプリへ反映します。
10. 画面右側のDebugタブへセンサーからデータが表示されるのを確認します。

#各センサー値の取得
各センサーの値を個別に取得するフローを以下にご紹介します。
[Watson IoT Platform - Node-RED - フローをコピーする方法](http://qiita.com/egplnt/items/84b244a50d8bdaced324)を参照して以下のフローをコピペします。
