The cornerstone of our project is Women Empowerment; by providing them a Smart Cradle System with a special focus on developing countries. This paper proposes the use of “Smart Cradle System" which involves the use of the Internet of Things. The proposed solution involves live monitoring of the child through a mobile application remotely. The smart cradle incorporates the use of a sound sensor for the detection of the child’s crying activity and automatically swings the cradle to soothe the child along with some slow music to make baby relax. The DHT11 sensor checks with the body temperature of the child and Humidity value. The solution also includes a wetness sensor to maintain the hygiene of the child. The proposed system uses the cloud service for remotely monitoring the child. In the current era, internet is an ecosystem within which IoT (Internet of Things) has continuously enhanced the physical and wireless connection of devices with less to no intervention of humans. According to a survey in 2019 there are 23.8 million (two-third) working women with babies; managing work along with babysitting is a hectic task. Thus, internet of things (IoT) based baby monitoring system for smart cradle is implemented to fulfil baby’s needs and provides intimation to parents. A smart baby cradle provides parents/guardian an automatic system which helps these parents monitor and comfort the baby through online streaming via camera. The cradle includes MP3 player for soothing music, temperature detector and bed wet sensor are embedded into ESP32 wroom (microcontroller) platform.     The processor is programmed in PYTHON language which intelligently performs the specific task. The system detects humidity and temperature of the surroundings near cradle. The USB camera gives the live streaming about the baby in the cradle. The sound sensor attached senses the sound of the baby and gives signal to the Arduino. Arduino activates the DF mini player which inturn plays soft music stored in MMC Card through speaker. When the baby is crying which is detected by the sound sensor, the Raspberry Pi turns ON the servomotor and moves the cradle. Wetness sensor is also used to sense the wetness in the cradle to ensure the hygiene condition of the baby. All the four parameters are sent to the blynk app. Also we can see the visuals of the baby in cradle through web browser.
