Condensation Monitor Measure the current environment condition at outside and inside and make caution or warnings related to condensation. Support UART over BLE. It works with nRF Toolbox. 結露モニタ 屋内外の環境情報を計測し、結露に関する警告あるいは注意を出力します。 nRF Toolboxと一緒に動作し、UART機能でBLE経由でメッセージを出力します。 ドキュメント https://developer.mbed.org/users/takafuminaka/notebook/information-about-my-condensation-monitor-for-mbed/
