Development Of Posture Alert System

Abstract

Prolonged sitting in sedentary work environments frequently results in improper posture, which can contribute to chronic back pain and various musculoskeletal complications. This study proposes a wearable real-time posture monitoring system designed to encourage healthier sitting behavior through continuous feedback. The system employs an MPU6050 sensor, which integrates an accelerometer and gyroscope, to measure the orientation and inclination of the user's spine. An ESP32 microcontroller processes the sensor data to evaluate posture by comparing measured angles with predefined threshold values.When the system detects a slouched or incorrect posture, it immediately activates an audible buzzer to alert the user and displays visual feedback on a Liquid Crystal Display (LCD). The display provides posture status messages such as “Good Posture” or “Please Sit Upright.” The proposed device offers a cost-effective, lightweight, and non-intrusive solution for posture monitoring and correction. Furthermore, the use of the ESP32 platform enables potential future integration with Internet of Things (IoT) applications for remote monitoring and data analysis. Experimental evaluation demonstrates that the system effectively assists users in maintaining correct posture and reducing prolonged periods of poor spinal alignment, thereby supporting long-term musculoskeletal health.
