Design and Implementation of the Crib Monitoring System

This paper designs a crib monitoring system based on the STM32 microcontroller. The system uses temperature and humidity sensors to collect the ambient temperature and humidity. The microcontroller processes and analyzes the collected data, and displays it through the display module. When the temperature is higher or lower than the preset threshold, the fan module or heating module is started to adjust the temperature. The temperature threshold is set by the key module. The system will give an alarm when the baby touches the fence to prevent the baby from falling. The system can adjust the motor speed through the key module, aiming to control the crib swing speed. Lullabies are played through the voice broadcasting module to help the baby relax and fall asleep; In addition, the temperature and humidity information is uploaded to the mobile terminal for real-time display through the Bluetooth communication module, and the mobile terminal can also control the motor speed, playing, and music switching. The test result shows that the crib monitoring system has the characteristics of fast response speed, high identification accuracy, and good stability. It can provide a theoretical basis for the actual crib production, and has a certain reference value.
