WICED Sense
開発キットなので、計測した結果を見せてくれるだけ。例えば、気圧が下がったらアラートを出すとか、計測結果を記録してグラフ化するといった機能はない。あくまでも開発キットなので、後からアプリを開発する環境は用意されている。
スマホ用アプリのソースコードも公開されている
Beaconやワイヤレス充電に対応し、セキュリティ保護されたワイヤレス・ダウンロードでファームウエアを更新することも可能だ。Bluetooth Smartの通信でiPhoneとセンサータグをペアリングする設定も、数回のタップ操作のみで完了し、センサーを早速読み取ることができる。

特定の条件を満たす時のみデータをMTQQブロかー送るするにはどうすればいいか？
cylonの詳細を調査
センサーの場合、何を目的にするかにもよりますが、
ジャイロなどの動き系であれば、動いたことを検知してデータを送るのが良さそうです。
気温等のデータの場合は一定間隔で送る必要がありますが、例えば5分単位のデータがあれば十分なのではないかと思います。 ジャイロ・加速度センサーはしばらくいろいろと動かしてみて検証し、しきい値を決めて送る送らないを判定するロジックを入れようと思います。
