Baby Cradle Monitoring System Using IOT

The Baby Cradle Monitoring System Using IoT is an innovative solution designed to enhance infant safety by continuously monitoring environmental and physiological conditions inside a cradle. The system employs NodeMCU (ESP8266) as the primary microcontroller, integrating multiple sensors including DHT11 (temperature and humidity), water/rain sensor, sound sensor, and soil moisture sensor to detect critical parameters such as ambient temperature, wetness, infant crying, and diaper moisture levels. A servo motor is utilized to simulate cradle rocking motion, while a buzzer provides immediate local alerts in case of anomalies. All sensor data is transmitted in real-time via the MQTT (Message Queuing Telemetry Transport) protocol to a cloud-based IoT panel app, enabling remote monitoring and notifications for caregivers. This paper presents a comprehensive study on the system architecture, hardware-software integration, data transmission methodology, and experimental validation. Results demonstrate that the system effectively ensures infant comfort and safety by providing timely alerts and automated responses. Future enhancements include the integration of machine learning algorithms for predictive analysis of infant behavior and the implementation of solar power for energy efficiency.
