Project Introduction
This project is based on the STM32L0 series ultra-low-power microcontroller, paired with the XINYI Technology XY-MBD40A Bluetooth module, AHT20 temperature and humidity sensor, SG90 servo, and a dedicated APP. It can control lights (on/off), read temperature and humidity, consumes 100uA in standby mode, and a 1000mAh lithium battery can last for one year, rechargeable via a Type-C interface.
This product primarily focuses on power consumption control, making significant progress from an initial 400uA to the current 100uA. For further improvements, optimization can target the STM32's standby mode, reducing leakage current between the servo signal line and STM32, and optimizing the Bluetooth module's broadcast interval.
