Sawant, Dipali V. Badgujar, Prof. Dnyaneshwar V. Kudande Department of Computer Engineering, SRTTC college, Maharashtra, India ABSTRACT IOT is the vast area which is getting upgraded in the field of security as well as in the field of industry. In the field of security the IOT also plays an important role for the child's safety. To overcome the problems of guardians we have used the radar sensors and the obstacle sensors for identifying the child problem and for maintaining his safety. In this proposed system we have worked on child safety where we have detected the danger zone in which the child enters and the signals or alarm buzzers are given to the guardians. Keywords : Internet of Things (IOT), Deep Learning for Object Detection, Radar Sensors for Height Detection. I. INTRODUCTION Nowadays most of the parents face difficulties in managing their children due to their busy schedule. Every time they are not able to watch their child. To overcome their problem we have worked on a small IOT device which will inform to the guardian about the child danger and the device will send the signals to the guardians mobile device or else by alarm .The main motive of this device is to minimize the problem of guardian and also to protect the child form various types of danger. System consist of following points: 1. harmful object detection using deep learning techniques. 2. Height detection by using a Radar sensor to save the baby from falling down from height. 3. sounds an alarm when the baby enters the danger zone. II. RELATED WORK a. Survey on existing System The existing systems monitor the baby and give an update of his health and mind status of the children. hadoop and C4.5 algorithms for predicting the disorders using the collected data. Baby cradle system uses the Internet of Things, Amazon Web Service, Baby Cradle and provides parents a smart system to help these parents monitor and comfort the baby. b. Survey of child monitoring system [1] Chinlun Lai, Lunjyh Jiang,“An Intelligent Baby Care System Based on IoT and Deep Learning Techniques”, in the year 2018,international scholarly & scientific research & innovation. a. Methodology: This system uses Baby care system, internet of things which works for infant care work. It also uses deep learning techniques. b. Findings and Application: This device monitors the baby’s conditions such as position, body’s temperature, and posture through deep learning which helps parents to know the baby’s condition. c. Remark (Future scope and conclusion): The assistance of the proposed baby care system, it can detect the potential dangerous events immediately and thus prevent the baby from possible harm or death
