Smart home lighting architecture
The architecture behind this smart home lighting system involves an LED driver
(HVLED815PF) to supply and monitor the LED load, an STM32L05x microcontroller to
manage the board, a low power sub-GHz module based on the SPIRIT1 RF transceiver
(SPSGRF) for external communication and a remote application running on an Android
®
mobile device to display status information and generate remote commands.
Cloud-based IoT functionality is supported with the introduction of a separate ST wireless
bridge (STEVAL-IDI004V2) or through a remote controller (SP1ML).
