The STEVAL-MKSBOX1V1 (SensorTile.box or BlueBox) is a ready-to-use box kit with wireless IoT and wearable sensor platform to help you use and develop apps based on remote motion and environmental sensor data, regardless of your level of expertise.
Up to now the SensorTile.box from STMicroelectronics was used to collect the sensory data such as temperature, humidity and more, which was then sent to Microsoft Azure IoT Central platform.
In few month STM will extend the IoT support to other principal dbase platform (Amazon, IBM, etc).
