Smart pre-examination health care system for doctors based on ARDUINO microcontroller.

Currently, the people and the hospital management wasting their time and wealth because of the lack of a smart system in the pre-examination process for patients. This paper has presented an approach to designing a healthcare system that collects the necessary body conditions by using a microcontroller-based smart system and collected information reports to the authorized smartphone. Smart things and the internet of things make life easier. The Health Care System is the cheapest healthcare device for patients and doctors. It provides a solution for the measurement of body parameters like ECG, Temperature, Moisture, and Heartbeat, and it also detects the body condition, using Arduino UNO. The LCD screen contains a very simple GUI Interface for reading all the parameters for the patient and doctors. if there is something wrong with the patient the RED LED will light up, and the system will generate an alert when it is required which means at the time of any critical conditions and notifications about the medicines. As for the yellow light, it will only light up when the patient presses the button, and this means that the patient is not in danger but wants to talk to the doctor or nurse.
