BAD POSTURE DETECTOR MONITORING SYSTEM

Abstract

According to the most recent medical information and physiotherapy technology, there are several flaws in monitoring spinal problems among people of various ages. For example, about 16 million adults, or 8% of all adults, suffer from persistent or chronic back pain, limiting their ability to engage in certain daily activities. Back pain is currently the sixth most expensive condition in the world. Many of the condition's indirect costs are related to missed work days and disability benefits. People with back pain is a word used in this profile to denote adults who have persistent or chronic back pain that limits their daily activities. So, by building a system named "Bad Posture Detector Monitoring System," I've decided to aid medical institutions in providing a smart device to identify bad spinal posture, particularly for students and employees who are still working from home. The system works by detecting the human’s existence using the PIR sensor and if there’s a human detected sitting on the chair, then the ultrasonic sensor will be activated. After the ultrasonic sensor was activated then the distance between the user's back and the chair headrest will be detected, which is then shown as the distance that is appropriate for optimal spinal posture. If the distance indicated by the sensor indicates a faulty posture, an alarming noise or interruption will be triggered to warn the user to improve their posture. The buzzer and LED are the noises mentioned. If the distance between the chair headrest and the user's back is greater than 2 cm, the buzzer will beep and the LED will light up, but if the gap is less than 2 cm, nothing will happen. Additionally, the data will be presented on the Arduino IDE's serial monitor. The proposed system may be readily installed on the chair headrest without interfering with the users' comfort when sitting in the chair. As a result, by using this device, students and employees may experience fewer spinal difficulties, and chronic spinal disorders may be avoided sooner.
