This Smart House Demo was created within the Atmosphere low-code web IDE. It is powered by the CYW20819 Dual-Mode Bluetooth 5 MCU. The CYW20819 Arduino Eval Kit is used as a basis for this prototyping platform. It is placed within an actual Smart House enclosure, and connected to some external sensors as well as a relay to control a small fan. The CYW20819 Arduino Eval Kit sends sensor data via BLE to an Atmosphere Mobile App (ready-to-use, provided by Atmosphere). Through the mobile app a user can set the fan to turn on/off based on a certain set point.
