Reducing energy consumption in home automation based on STM32F407 microcontroller

One of the most important problems in home automation is dedicated to reducing energy consumption. Different methods have been proposed which are mostly aiming for low-costs approaches. This paper offers a low-cost solution based on STM32F407 microcontroller. The solution has been implemented on a house situated in a four-season geographical area. The obtained results are extremely promising, indicating a reducing of the energy consumption with approximately 15%.
