node.jsによるTIセンサーの受信
OpenBlocks IoT BX1とインテルEdison KitでTI社製のCC2541 SensorTagを使用するためにnode-sensortagを使用します。
node-sensortagを使用することで以下の情報が取得できます。
IR Temperature Sensor（温度）
Accelerometer（加速度）
Humidity Sensor（湿度）
Magnetometer（磁気）
Barometric Pressure Sensor（気圧）
Gyroscope（ジャイロ）

※setIntervalの設定値（10秒）に一度データを取得します
※node-sensortagのサンプルプログラムを修正して使用
3. 動作確認
