Developing Internet of Things (IoT) Device for Saving Children from Being Left in a Car

Abstract

Recently, there have been news reports about the death of children left in cars or kindergarten vans. This paper presents a device that can prevent the death of the children by using IoT devices and mobile applications. The researchers have an objective of innovating a
way to notify overseers when a child has been left in a van by using a mobile application and to allow parents to track their own children by using an IoT device and mobile application. We placed a device in a car that would send data to a cloud server that we created and used a mobile application to watch the webcam in the car, edit information of passengers, and receive the data from the device. We have tested the system from 1^st Jan to 31^st Jan 2021 with 30 testers and received satisfaction assessments to measure performance and feedback of testers to improve this device. For the result, we made two parts of satisfaction assessment, which are usefulness, and field of use, containing 7 questions. The results show that this device has satisfaction’s mean() = 4.20, standard deviation (S.D.) = 0.60, and level of satisfaction is vary.
