Arduino Based Prolonged Suspicious Inactivity Monitoring of Old Aged People

The proposed framework includes the construction of a an astoundingly financially sharp and outrageous discernment device that fits at door frames in order to the moving in and out of a particular fundamental door of an old aged person and when suspiciously for too long the subject does not move out, it sends a notification to any of his family members or relatives about the matter to be of probable concern. It can be utilized in apartments as well as houses, where an old aged person lives totally alone, in case there is no caretaker and the adults of the family are staying apart, or even if children in their late teen age stay alone, or any solitary residents having potential medical or societal risks. The project is based on the concept of the Internet of Things (IoT), run by an open-sourced hardware – a microcontroller integrated circuit in the form of a circuit board named Arduino-UNO, where the centralized controller is an ATmega328 P Controller. The system includes an Ultrasonic Sensor as the key sensor, and a GSM 900 Module as sender of SMS. When it is sensed that the person have not moved from the particular door, tentatively the washroom door, because it is a must, for quite a long time like half a day or full, it sends an SMS to the pre-loaded contact number.
