Design and Implementation of Intelligent Crib Based on Internet of Things Technology

This paper presents the design of an intelligent crib system based on IoT technology, with an STM32 micro controller as the core controller. The system integrates a WiFi module, temperature and humidity sensors, an air quality sensor, a sound sensor, a raindrop detection sensor (for bed-wetting detection),a motor module (for rocking), a fan module, a music playback module, an alarm module, an LED display module, and button control modules. The sensors enable real-time monitoring of the crib environment, while cloud-based algorithms ensure accurate infant cry recognition. The motor and music modules help soothe the baby, the fan module improves air quality, and the alarm module alerts caregivers promptly. Real-time data is displayed on the LED screen, and remote monitoring and configuration are supported via a mobile App. The proposed smart crib system features fast response, high recognition accuracy, and strong stability, meeting the practical needs of infant care.
