Abstract: An IoT-based smart baby monitoring device offers a practical solution for working parents by automating childcare tasks in specific areas. The system integrates sensors and a microcontroller to monitor the baby’s movements and environment, activating devices only when necessary to conserve energy. A proposed implementation involves a smart cradle equipped with various sensors and IoT capabilities, enabling parents to monitor their baby’s activities remotely from anywhere in the world. The system is designed using a NodeMCU Controller board, which collects data from sensors such as PIR motion detectors, moisture sensors, temperature and humidity sensors, and harmful gas detectors. This data is then transmitted via Wi-Fi. For example, if the ambient temperature exceeds a preset limit, a fan automatically activates to maintain a comfortable environment. Additionally, an external webcam (such as ESP32 CAM) can be integrated to provide real-time video monitoring of the baby’s condition. Sensor readings are stored on a Blynk server, which also powers the mobile notification system. If the baby cries, parents receive instant alerts through the Blynk app, ensuring they are always aware of their child’s status even when away from home. This smart cradle design offers an efficient and reliable solution for modern childcare needs.
