Calmnest: IOT Based Smart Cradle Using Controller Ble Sense

Abstract

This paper presents CalmNest, an IoT-based smart cradle designed to enhance infant safety and comfort using a microcontroller integrated with BLE Sense technology. The system monitors key parameters such as motion, sound (cry detection), temperature, and humidity in real time. Upon detecting abnormal conditions, the cradle automatically performs soothing actions, including controlled rocking, and sends alerts to caregivers via a mobile interface. The use of Bluetooth Low Energy (BLE) ensures low power consumption and efficient wireless communication. The proposed system offers a reliable, cost-effective, and user-friendly solution for remote infant monitoring. Experimental results demonstrate improved responsiveness and reduced caregiver intervention, highlighting the potential of IoT-enabled smart childcare systems.
